Which force slows down a ball when it moves?
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
Is friction useful?
yes friction is very useful because it help objects not to slide or slip
Friction is an example of what force?

What are the factors that determine the friction force between two sliding objects?
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
How is force of friction useful?

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.

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.
Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Which force slows down a ball when it moves?
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
