What is the mathematical equation for friction?
An important formula is that friction = (coefficient of friction) x (normal force).
What force occurs when objects come into contact?
Friction.
Force that resists motion between objects in contact?
Friction
What is the metric unit for friction?
A friction is a force, so it would be measured in newtons. The coefficient of friction, on the other hand, is a ratio between two forces, so it is dimensionless.
What is The relationship between weight and frictional force?
Weight is extremely useful in determining the frictional force on an object. Say we have a box on a level surface. The box has a weight of mg(mass times the gravitational constant). Since the box is still, and it is being supported by the ground, there is an equal and opposite force that is being exerted on the box by the ground, which pushes it up. This is known as the normal force. The force of Friction is defined as the greek letter mu(which is the coefficient of friction for the two materials against each other)times the normal force, which in this case is mg. Mu also varies depending on wether or not the box is moving in contact with the ground. A different coefficeint of friction is used instead of the one when the box is at rest. The frictional force on the object is always greater when the object is at rest than when it is sliding. Hope this helps!
How is force of friction useful to us?
it is a mebr in the gavde
Friction is inveitable but it has disadvantages why?
Friction is a force that must be overcome for no useful purpose. It takes energy to do this, and thus is wasteful.
What is the force that brings nearly everything to a stop also useful for mountain climbers and baseball players?
That force is called friction.
When friction is a useful force?
Friction is a useful force in situations where you want to stop or slow down an object, like brakes on a car or shoes on the ground providing traction. It is also important for tasks that require grip or control, such as writing with a pencil or turning a screw.
What is frictional force and its uses?
Friction is a force that is generated when two surfaces rub against each other. It is useful for preventing slipping or sliding.
Is friction a useful force?
Yes because when you play a game of tug of war you just pull it and the other push it
When is friction a useful force that acts between objects?
Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
How to find the friction coefficient in a given system?
To find the friction coefficient in a given system, you can use the formula: Friction coefficient Force of friction / Normal force. The force of friction is the force resisting the motion of an object, and the normal force is the force exerted perpendicular to the surface the object is on. By dividing the force of friction by the normal force, you can calculate the friction coefficient.
What is one way that friction is ueful?
Friction is useful in helping to prevent objects from slipping or sliding when a force is applied to them. This is why we are able to walk, drive vehicles, and grip objects with our hands.
Which is the larger the kinetic friction force or the statical friction force?
Statical friction
