Item RG048002: A weight will have more energy when it is 6 feet above the ground than when it is 3 feet above the ground because the higher an object is the more energy it has.
A weightlifter is practicing in a gym. He bends down to pick up a weight and then lifts it over his head.
When will the weight have more energy and why?
- The weight will have more energy when it is 3 feet above the ground because the lower an object is the more energy it has.
- The weight will have more energy when it is 6 feet above the ground because the higher an object is the more energy it has.
- The weight will have the same amount of energy when it is 3 feet or 6 feet above the ground because the amount of energy an object has does not depend on how high it is above the ground.
- The weight will not have any energy no matter how high it is above the ground because objects don’t have energy, only people do.
