2 cards from this section. Quick, good the night before a test.
Define static friction in your own words.
Consider how static friction works with stationary objects.
What happens to static friction when you start pushing a stationary object?
Think about the forces acting when you exert pressure.
What type of friction acts when an object is at rest?
Think of what keeps objects stationary.
True or False: Kinetic friction is usually greater than static friction.
Consider how forces change upon movement.
A 75 kg person stands on an incline of 30 degrees with respect to the horizontal. Calculate both the static friction force and kinetic friction force if the coefficient of friction is 0.5.
Remember to calculate both the forces acting due to gravity.
Discuss how the coefficient of friction would change if the surfaces of contact were more textured versus smoother.
Consider real-life examples of materials and their friction in daily activities.
