Which has more kinetic energy? Two 50kg cars .....one traveling at 30mph and the other traveling at 50mph.

50 kg car traveling at 30 mph

50 kg car traveling 50 mph

1 answer

The 50 kg car traveling at 50 mph has more kinetic energy. Kinetic energy is directly proportional to the square of the velocity, so the car traveling at 50 mph will have significantly more kinetic energy than the car traveling at 30 mph.
