Question

Potential Energy can be described as Ep= m.g.h where m = mass which is measured in kilograms, g = acceleration of gravity which is measured in meters per second (m/s2), and h = height which is measured in meters . What is a possible unit measure for Potential Energy

Answer 1

We need to analyze the units of each of the magnitudes and solve the operations between them:

$\begin{gathered} m\to kg \\ g\to\frac{m}{s^2} \\ h\to m \\ m\cdot g\cdot h\to kg\cdot\frac{m}{s^2}\cdot m=kg\cdot\frac{m^2}{s^2} \end{gathered}$

A possible unit for potential energy is kg*m^2/s^2.

Also we can use distributive property to replace some of the units by derived units, for example, Newtons:
