Question

1. what is elastic potential energy?

Explanation:

Elastic potential energy is the energy stored in an object when it is deformed elastically. For example, when a spring is stretched or compressed, it has elastic potential energy. The formula for elastic potential energy of a spring is $U = \frac{1}{2}kx^{2}$, where $k$ is the spring constant and $x$ is the displacement from the equilibrium position.

Answer:

Elastic potential energy is the energy stored in an object due to its elastic deformation. For a spring, it is calculated by $U=\frac{1}{2}kx^{2}$.
