Question

An equation for potential energy states U=mgh. If U is in joules (J), with m in kg, h in m, and g in

$m/s^2$

, find the combination of SI base units that are equivalent to joules.

Solutions

VerifiedSolution A

Solution B

Step 1

1 of 3$\textbf{Given: }$

The potential energy is given by the following relation $U = m g h$. According to SI units. The potential energy is in joules. The mass is in kilograms. The height is in meters. As we know the gravitational field of the earth $g$ is in $\mathrm{~m/s^{2}}$.

$\textbf{Required: }$
