B Energy required to bring 1 kg 1000 meter above the surface of the Earth

[Mikael17]

How can i calculate the Energy required to bring 1 kg 1000 meter above the surface of the earth ?

Look up "gravitational potential energy". You need the difference in its value for a 1000kg mass at the two distances from the center of the Earth.

Good for you. Will you have access to the lazy version if you see something like this on a test?

I had a friend and colleague who was asked a question he didn't know on an oral exam.

Him: "Well, I know where to look it up if I ever need it."
Prof: "But you need it now."

In either case this one is so easy/basic you really should be able to memorize it, plus knowing how it works you can deconstruct, rearrange and apply it to other kinds of energy/problems.

There are formulae and there are basic principles which can often be expressed by formulae. To understand and know a basic principle it is necessary for you to be able to put names (words) to the basic symbols that a shorthand formula tells you.
