Question

A ball is drop from the top of a building. You choose the top of the building to be the reference level while your friend choose the bottom. Explain wether the energy calculates using these two reference level is the same or different for the following situations

Answer 1

Explanation:

Based on the references, the calculated potential energy is the same if the reference used is the same or different.

Potential energy is the energy due to the position of a body.

It is the energy at rest in body.

The change in potential energy is given as:

    ΔE  = E₂ - E₁

E₂ is the final potential energy and E₁ is the initial potential energy.

Since when the body comes to rest after falling through a height, the final potential energy is 0.

The change in potential energy does not depend on the reference.
