Question

which equation shows the correct relationship between mechanical energy, kinetic energy, and potential energy?
me = ke + pe
me + ke = pe
me = ke - pe
me + pe = ke

Explanation:

Step1: Recall energy - concept

Mechanical energy (ME) is the sum of kinetic energy (KE) and potential energy (PE).
So the equation is ME = KE + PE.

Answer:

A. ME = KE + PE
