Question

A 1kg mass has a potential energy of 1.0 J relative to the ground, what is at a height?

Answer 1

0.10204 by formula of P.E mgh by taking g-9.8

Answer 2

Answer:

The correct answer to this question is 0.102m.

Explanation:

Given - A 1kg mass has a potential energy of 1.0 J relative to the ground.

To Find - Write what is at a height?

Because potential energy is a relative term, it is given by mgh when the ground surface is used as a reference.

So 1 × 9.8 × h = 1J all are in SI units.

So height is  = 0.102m.

Potential energy, is stored energy that depends upon the relative position of various parts of a system. Spring has more potential energy when it is compressed or stretched. A steel ball has greater potential energy when it is elevated above the ground than when it is dropped to the ground.
