This simple and fun demonstration teaches how torque, speed, and friction can influence the distance an object travels. So many interesting physics concepts can be taught using these two pull back cars; one with high torque (low gear) and the other with low torque (high gear). When pulled back the same amount and then released, both cars travel approximately the same distance, but one gets there in a hurry, while the other takes its time. Approx. 5 cm (2 in.) long. Styles may vary.
