Study Notes

Elastic Potential Energy of a Spring

The formula for the elastic potential energy of a spring is: U = (1/2)kx²
This formula represents the energy stored in a spring due to its deformation.

Spring Constant

The spring constant, k, indicates the measure of a spring's stiffness or how much it resists deformation.
A higher value of k means a stiffer spring, while a lower value of k means a more flexible spring.

Units of Spring Constant

The units of the spring constant, k, are Newtons per meter (N/m).

Change in Length of Spring

The change in length of the spring is known as the deformation or displacement of the spring.

Deformation

The deformation, x, represents the amount of compression or stretching of the spring from its equilibrium position.
It is a measure of how much the spring is compressed or stretched from its original length.
