Item EG006006: When a person is riding a bike, the person has more motion energy than the bike because the person weighs more than the bike.

A man is riding his bike. The man weighs 150 pounds and the bike weighs 25 pounds.

Does the bike or the man have more kinetic energy (motion energy) and why?

  1. The bike has more kinetic energy than the man because the man is giving the bike his energy.
  2. The man has more kinetic energy than the bike because the man is alive but the bike is not.
  3. The man has more kinetic energy than the bike because the man weighs more than the bike.
  4. The bike and the man have the same amount of kinetic energy because they are traveling at the same speed.
