Item RG050002: A flower pot on the taller post has more energy than a flower pot on the shorter post because it is higher above the ground.
Two flower pots are sitting on two different posts as shown in the picture below. The flower pots are exactly the same.
Which flower pot has more energy and why?
- The flower pot that is on the taller post has more energy because it is higher above the ground.
- The flower pot that is on the shorter post has more energy because it is closer to the ground.
- Both flower pots have the same amount of energy because how far an object is above the ground doesn’t determine how much energy an object has.
- Neither flower pot has any energy because they are not moving.
