What is friction?
Think about what happens when you slide something.
Name a factor that affects friction.
Consider how different surfaces interact.
What opposes motion between two surfaces?
Remember the force that slows objects down.
True or False: Rough surfaces have less friction than smooth surfaces.
Think about surface interactions.
A block with a mass of 10 kg is resting on a surface. If the coefficient of static friction is 0.4, what is the maximum static frictional force?
Remember to calculate the normal force using weight.
If a car has a weight of 1200 N, what is the frictional force if the coefficient of kinetic friction is 0.2?
