Drop stacks of coffee filters, measure their steady fall speed, and show how air drag grows with speed.
Measure the terminal velocity of coffee filters of different mass and test whether drag force is proportional to the square of speed.
Crash two toy carts together, measure speeds from video, and test whether total momentum is conserved.
