Car Race (testing gravity) Gather: Cardboard or foam core for a ramp; Toy cars of different sizes and shapes; Low table or chair to prop the ramp on; Painters tape; Use the tape to create a "race track" and to fix the ramp to the table. As the trap releases, the car is pulled forward. However, the heavier car will gain more momentum. Experimentally, the acceleration due to gravity is valid because when the ramp is set to a 90 degree angle, it essentially has no slope, so objects that are set at a 90 degree angle experience free-fall which is 9.8 m/s2. In this experiment, your kids will learn how different surface textures and the different amounts of friction produced will affect the distance the car travels. As the cart rolls down the ramp, there are three forces that act upon it. Another activity that involves experimenting with angles is this African Sunset Shadow Tracing Art.
