True/False: Air resistance is a force that only happens when an object is moving. True/False: Air resistance is different than the force that can happen with the wind, since the wind can push on an object that isn’t moving. True/False: The forces due to wind, air resistance, and friction between a sliding object and a stationary one always point in the opposite direction of motion. True/False: The force of friction between a sliding object and a stationary one is greater when the surfaces are rougher because the bumps and grooves on the two surfaces bump into each other. True/False: If you drop three regular-size pieces of paper, all crumpled a different amount, from a high wall, the initial force of air resistance will be the same on all three pieces of paper because they are all light.

True/False: If you drop three regular-size pieces of paper, all crumpled a different amount, from a high wall and all three eventually reach terminal velocity before they hit the ground, the air resistance will be the same on all three at that point.
Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.
