Force of Friction (Ff)

Front

What does the coefficient of friction describe?

Back

How rough or smooth two surfaces are rubbing together.

Front

What type of friction is not moving?

Back

Static friction.

Front

What is the coefficient of static friction if it takes 44 N of force to move a box that weighs 86 N?

Back

0.51

Front

Friction is a force that acts in an ___________ direction of movement.

Back

Opposite direction.

Front

Under what condition(s) will an object be in equilibrium?

Back

If the object is either at rest or moving with constant velocity.

Front

What is the formula for calculating the force of friction (Ff)?

Back

Ff = μ * N, where μ is the coefficient of friction and N is the normal force.

Front

What is kinetic friction?

Back

The frictional force acting between moving surfaces.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on moving objects.

Front

What factors affect the force of friction?

Back

The nature of the surfaces in contact and the normal force acting between them.

Front

What is the maximum static friction?

Back

The maximum force that must be overcome to start moving an object at rest.
