Question

The potential energy for a mass on a spring is proportional to the square of which of these quantities? A. mass B. frequency C. period D. displacement E. velocity

Answer 1

Answer:Displacement

Explanation:

Potential energy is present in a spring because the spring is elongated and some work is done it to elongate it.

The elastic potential energy present in a spring is given by $kx^{2}$

where $k$ is the spring constant.It may vary from spring to spring and $x$ is the displacement of the spring from its equalibrium position.

It is evident from the equation that potential energy in the spring increases as $x^{2}$ increases.
