What Is Stationary Friction by VPP VINACOM

What Is Stationary Friction

stationary friction is when friction is happening on an object that is stationary.(STATIONARY MEANS STAYS STILL, OR NO MOVEMENT)

How can friction move stationary objects?
friction can not move stationary objects, it just opposes the relative motion between them.

What kind of friction must be overcome to start movement of stationary object?
The type of friction that must be overcome to move a stationary object is called static friction.

The friction between objects that are stationary is called?
Static friction.

Friction that is between stationary surfaces is called?
Static friction.

What type of friction must be overcome in order to get an object moving?
Stationary or static friction is the friction for a stationary object that resists the initiation of motion relative to a surface or another connected object.

When is friction at its greatest stage?
When the object that the friction is acting upon is stationary.

What kind of friction must be overcome to start movement of a stationary object?
That is called static friction.

What is the definition of stationary friction?
Look for a Book Fool. >.

What is the force that causes stationary object?
Frictional force is a retarding force.It is friction that causes an object to become stationary.

When does energy causes friction?
when it moves to eliminate friction the energy must be stationary or at absolute zero temp

Friction between objects that are stationary is called what?
The friction between two stationary forces is called static friction. It is the friction that resists two objects to start moving against each other. Once in motion, the friction between two forces is called dynamic friction. Static friction tends to be greater than dynamic friction, which is why it takes more force to get a heavy box moving along the ground compared to keep it going.

What type of friction requires the use of extra force to start the motion of stationary objects?
this is called static friction

As the pull on a stationary object increases the force of static friction remains constant?
No. In order for an object to remain stationary, the forces on it must be balanced. If the pull on the object increases, the force of static friction must also increase.

What forces act on a stationary object question mark I know there's weight reaction force and a minute amount of friction but hasn't there got to be a force that opposes friction?
Actually, don't worry I know the answer to this particular question now. There is friction, weight (mxg) and reaction force. Movement opposes friction, but that isn't taking place when an object is stationary.

How brakes stop a bicycle?
By creating friction between a moving part and a stationary part.

Explain how friction affects the motion of an object?
Friction is speed's worst enemy. If no forces act on an object, it is stationary. If a force acts on an object, it keeps going forever until another force acts on it (such as friction!!!).

How is friction used to stop a bicycle?
Somewhere, a stationary brake pad will be pushed against a moving surface. If the bike is rim braked, brake pads will pinch the wheel rim. If the bike is drum or coaster braked, stationary pads will push out against the rotating shell of the hub. If the bike is disc braked, brake pads will pinch the rotor between them. And the friction between the moving surface and the stationary brake pads (together with the friction...

Why does applying the brakes on a bicycle cause it to slow down?
Same as on a car. Applying the brakes means that something stationary is pressed against a moving part. This generates friction, which turns speed into heat. It produces friction, because when the brake touches the rim of the bicycle, the bicycle slows down. (thats called friction) And after a while the bicycle stops A stationary part is brought into contact with a rotating part. The resulting friction slows the bike down.

What is the friction that hinders a stationary object from moving on a surface when a force is applied to that object?
Static friction. The frictional force is greater then the force applied, meaning the object can't move.

What kind of friction can must be overcome to start movement of a stationary object?
Static friction must be overcome. Once a force has been applied that starts the object in motion, the force of kinetic friction is less than its static counterpart.

What is liquid friction?
Friction = Light x Velocity Any Friction is simply the m/Z (Stationary Light Particles) within any piece of Mass being struck by Velocity. FRICTION = m/Z x AZ = mA = Force = Light x Velocity = FRICTION See EinsteinElectricitydotcom for an amazing example of Friction. EinsteinGravitydotcom

When you push on a stationary object and it doesnt move what kind of force is most likely opposing your efforts?
static friction

How do I calculate the velocity of an object which hits a stationary object if I know the mass of both objects and the distance the stationary object was moved what else must I know to calculate?
You need to know the coefficient of static friction and the coefficient of moving friction for both objects. The solution involves solving a differential equation so the math is non-trivial.

How do you reduce the impact force when hits another object?
If before .........increase the friction of surface If after............increase the mass of stationary object

Where does friction need to be small on a bicycle hub?
In the bearings that go between the stationary part - the axle, and the rotating part - the hub.

Does friction exist on a stationary object on a flat surface?
Yes. Otherwise, the slightest push would make the object move around.

What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).

Electrostatics is the study of?
Electrostatics is the study of electricity at rest. Break down the word: Electro=electricity and static=motionless, as in static friction or stationary.

What will happen in motion of vehicles if there were no friction?
They could never start moving - their wheels would keep spinning while the vehicle remained stationary.

Why Rolling friction is much less than sliding friction?
In sliding friction, an object is dragged over the ground, and the object is therefore moving in relation to the ground. The surface area of the underside of the object is in constant contact and motion with respect to the ground, and it is this underside surface dragging along the ground that creates the friction. In a wheeled arrangement, the surface area of the wheel is stationary with respect to the ground - it does...

A monkey hangs stationary at the end of a vertical vine. What two forces act on the monkey?
Gravity and friction. If both forces are equal, or if the friction is greater than gravity, the monkey remains on the vine. However, if gravity overcomes the force of friction, the monkey slides down the vine. none!

Why is kinetic friction less than the limiting friction?
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.

Why do meteoroids burn up in the earths atmosphere?
The heat of friction, and the heat of compression as the meteoroid, traveling upwards of 100,000 MPH, collides with the atmosphere which is essentially stationary.

Is The weight of the vehicle on the road surface is the reason that your car remains stationary when parked even on a steep hill?
Friction of the tires on the road surface ( I think so)

Which force resits motion between objects that are in contact?
The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.

What does the brakes do on a bike?
Brakes on bicycles does the same thing as on almost any vehicle. They slow the vehicle down by creating friction between a moving part and a stationary part.

When you are pulling a chair across a room what are you demonstrating?
Depending on your intent you could also be demonstrating: The grab and release of the frictional forces making a squeaking noise The shift in the position of the chair (up on its back legs) as the forces of gravity and your pulling balance out The fact the chair only moves when you pull it (Newton's First Law) The ease of pulling on a rug and a smooth wood floor The comparison of the engry required...

In which cases Friction can help the cause of motion?
There are many examples. The simplest ones would be walking or driving a car. Without friction it would be impossible to walk or drive, as there would be no surface to push away from. Wheels of a car would just spin and the car would remain stationary. Think about driving on ice (ice still have friction, its just lower).

What are the factors that determine the friction force between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction...

What effects does friction have between a wooden block and the surface its resting on?
If the block is stationary, friction has no active effects. However, if a force is applied to the block, it will continue to stay at rest until that force is more powerful than the force of friction. If the block is moving, the friction between the two surfaces is slowing the block down. This is because the surfaces of the two objects bond together (temporarily). When the object moves, the bonds break, and this releases...

What are the different types of stationary bikes?
You can have uprights and recumbents. Then there are the dedicated spinning bikes which can't coast. Then the simpler trainers that can coast. Then there are different methods of generating the resistance, either friction, or magnetic.

What is the definition of the push of air force?
Force on moving object by air friction: velocity2 * objects drag coefficient > Force on stationary object by wind: wind speed2 * objects drag coefficient

Kinetic frictions is the frictional force needed to start an object at rest into motion?
No, kinetic friction is the friction an object in motion across a surface experiences. Static friction is the frictional force an object stationary on a surface experiences. in nearly all cases static friction is stronger than kinetic friction. To elaborate, say we place a plate on a table. Sitting there, it experiences static friction, which resists our efforts to move it. Once we overcome that frictional force, the plate begins to move, but now it...

How does friction works on an object?
Depends on the object and enviornment. Is it stationary, accelorating, moving at a constant speed. There are a lot of differnent forces, is it round, square, flexible, solid or a liquid. There are PhD courses on this, not a simple concept.

Does friction always slow things down?
Well, it certainly can not speed things up (that would violate II law of thermodynamics). Motion can be converted into randomized heat, but randomized heat can never be converted into motion. So, yes, its 'always' slows things down (although not always, when object is stationary friction does nothing).

What is the difference between a stationary bike and a recumbent bike?
A stationary bike is like a real bicycle, but you don't go anywhere, and usually has only one wheel. Another name for this is 'exercise bike'. A normal bicycle can also be mounted on rollers to become a stationary bike. In a recumbent bike you're more leaned back with a seat like a chair and handles by your side. A recumbent is normally a road worthy machine, with either 2 or 3 wheels, but it...

What is the different between istatistic and kinetic friction?
I assume you mean static and kinetic friction. Static friction tends to be stronger and less predictable. For example, if you start applying more and more force to a stationary brick lying on sandpaper, it is almost impossible to predict when it will begin to move. Once it is moving, however, you can get a pretty consistent estimate for how much drag the brick is experiencing (kinetic friction). Modern cars have computers monitoring the brakes...

What is the definition of kinetic or dynamic friction?
Kinetic friction is commonly thought of as the friction between two objects while those two objects slide against each other. To determine the coefficient of kinetic friction (for an object under the influence of gravity on some surface), one needs to determine the angle at which the sliding object moves at a constant speed down the other object (think of a flat piece of rubber sliding down a flat plank of wood). This is different...

Why a horse has to apply more force to start a Tonga than to keep is moving?
Because of friction. Every object has 2 friction coefficient values (called Mu and with its own symbol) - one stationary, and the other while the object is moving. It always takes more force (N) to move an object from a stand-still then it does to keep the same object moving.

If action is always equal to reaction then how can a horse pull a cart?
I don't think you understand that Newton law: It is "Every action has an equal and opposite reaction." How a horse pulls a cart is based on what that cart has on it that reduces friction. Friction is the reaction that is created when an object is pulled (which is an action). Reducing friction by the addition of wheels on that cart makes it easier for that horse to pull that cart that may be...
