When an object is lifted 10 meters off the ground, it gains a certain amount of potential energy. If the same object is lifted 30 meters off the ground, its potential energy is a. The same b. Six times as much c. Three times as much d. Twice as much

Step-by-step explanation:

The potential energy involved here is gravitational and depends directly on the distance from the ground. That means, the more distance, more potenitial energy.

Notice that the first distance is 10 meters above the ground and the second distance is 30 meters. Therefore, the second distance means higher potential energy.

So, the potential energy is three times in the second case. The right answer is c.
