1-A car is lifted a certain distance in a service station and therefore has potential energy with respect to the floor. If it were lifted twice as high, how much potential energy would it have?
Answer: twice as much
2-Two cars, one twice as heavy as the other, are lifted to the same elevation in a service station. How do there potential energies compare?
Answer: The heavy object has more potential energy?
1 answer
Yes, the heavier car has twice as much potential energy as the lighter car.
