1
Q
How it acts
A
The force of friction is the force of a surface on an object acting along the surface.
2
Q
Direction of friction
A
The force of friction is in the oppposite direction of an objects motion (most of the time)
3
Q
What is mu
A
The coefficient of friction is Mu is not a force.
4
Q
What does mu tell us
A
The coefficient of friction is a number that tells how sticky to surfaces are
5
Q
Equation
A
The force of friction is equal to the coefficient of friction time the normal force
Ff= Mu x Fn
