Gravity Cars

Gravity and Friction, two forces we encounter constantly, can be harnessed to our advantage. Learn to put these forces to good use by building a car whose speed depends on weight, starting height, and gravity. Can you design a car with the greatest potential energy? This is your opportunity to make predictions and record your hypotheses. Distribute weights in various ways and learn what works best. Get creative and design a car that is truly yours. Further explore friction on different surfaces. Keep investigating for days to come!
