When a spring is compressed, its potential energy is what?

When a spring is compressed, its potential energy increases. Potential energy is the energy stored in an object due to its position or condition.

In the case of a spring, when it is compressed or stretched, energy is stored in it. This energy is called elastic potential energy.

The more you compress the spring, the more energy is stored in it. This energy can be released when the spring returns to its original shape. For example, in toys or mechanical devices, springs are used to store and release energy.

The formula for elastic potential energy is:
PE = ½ kx²
where k is the spring constant and x is the displacement.

This shows that energy increases with the square of compression or stretching.

Compressed springs are used in many applications like shock absorbers, pens, and machines.

Thus, compressing a spring increases its potential energy, which can later be converted into motion.
