From where do objects when lifted to a height gain potential energy?

Answer 1

The potential energy gain in an object that's lifted is taken directly from the force that is required to raise the object.

Example: I pick up a rock off the ground and place it on a table. That rock now has the amount of potential energy equivalent to the amount of energy it took for me to lift it and place it there.

Answer 2

Distance, (implying there will be an acceleration):
IE: put a mirror on the floor, drop a billiard ball 1 inch from the mirror, it probably wont brake.
Now drop the same ball 10 feet from the mirror, it will most likely brake the mirror!



*Do not try this at home;)

Edit: If you brought that billiard ball from another planet, to the earth, (not lifting it from the earth, but holding it as you come out of the space ship, from that 10 foot staircase coming out of the space ship) it would still have more potential energy if you drop it 10 feet than 1 inch! Ok, its still w=fd but d is the key, no matter how you shake that object (thus doing work) if you simply drop it, the potential energy will still increase or derease depending upon how high you hold it before dropping it!!!

Answer 3

When you lift an object, you are doing work on it by exerting a force on it, and in the process you have used up some energy of yours. Where has this energy gone? Remember it can neither be destroyed nor created. While doing work on the body in the process of lifting it, some energy which you spent is transferred to the body and is stored in it.

Answer 4

Since work is done against the force of gravity, the energy needed to lift (which is a kinetic energy) is converted to potential energy. Without gravity, there would be no work and no potential energy. So, in a weightless environment, if you push an object, it continues to move and you would move in the opposite direction!

Answer 5

Objects when lifted to a certain height, the quantity (unit) of potential energy comes less, not lossing. Kinetic is on the contrary, just leaving it, the kinetic enervy of a falling object increases gradually.

Answer 6

from the work done moving them to the hight.
work = force x distance
= energy used to lift it
= increase in gravitational potential energy

Answer 7

the first element i could communicate about is that the "merchandise" turns right into a "field" later contained in the question. that's healthier to leave a unmarried call for an merchandise so as now to not confuse - only a diploma of readability :>) U do not favor to apply a formulation - in simple terms information... IF U do artwork ON an merchandise that LIFTS it, then that artwork will enhance the GPE of the article and if the in simple terms element that artwork does is to extend the GPE of the article, then the GPE enhance = artwork finished = 16 J GPE = 16 J

Answer 8

By lifting it you did some work by going against gravity which tried to keep it on the ground.

Answer 9

when we lift an object the amount of work done by us in lifting the rock is stored in it in the form of p.e
