ACT
Students roll miniature cars down a ramp and measure their speed and acceleration every 10 cm. Students can vary the type of car, height of ramp or the ramp material. Student change one of these variables to investigate how the car's speed and acceleration change. Speed and acceleration can be graphed. The speed of each car during any one trail should increase linearly but it's acceleration should remain constant. The graphs can be compared and the slope differences discussed.
