Double the first potential energy.
The same amount of potential energy again.
True. It has "potential energy", in that gravity could be used to convert that "potential" energy into actual kinetic energy.
The potential energy is 147 joules.
Elastic potential energy can be found when you are stretching a spring. Any kind of elastic energy can be found when you are stretching or compressing an object.
The train is expending mechanical energy to be lifted higher in the earth's gravity well. As it is lifted higher, it is collecting and storing potential energy because of the fact that it is in that gravity well.
When an object is lifted from the ground, it has potential energy because of it's position.
The same amount of potential energy again.
Double the first potential energy.
kinetic energy being enacted. this energy is giving rise to potential energy too, as the item is being lifted into the air. When an item is lifted, it is given potential energy, as this potential energy is what fuels its future descent. So, when moved, kinetic energy is both moving the object, and storing potential energy for future use.
3 times the original potential energy

The potential energy increases because of the weightlifter lifting it above his head (Hope this helps)XP
It will withhold two times as much potential energy as before.
