Think of the friction when starting to move.
What type of friction opposes the initiation of motion?
Think about what happens before something starts moving.
True or False: Kinetic friction is greater than static friction.
Which friction is harder to overcome?
A box weighing 50 N rests on a rough surface with a coefficient of static friction of 0.4. Calculate the maximum static friction force.
Use the coefficient of static friction!
Explain why rolling friction is generally less than static and kinetic friction.
