Formula for Calculating Potential Energy of a Deformed Spring

The formula for calculating the potential energy of a deformed spring depends on the type of deformation and the characteristics of the spring. There are different formulas for different types of deformations, such as stretching or compressing the spring.

1. Potential Energy of a Stretched Spring: - When a spring is stretched or extended, the potential energy can be calculated using the formula: PE = (1/2)kx^2. - PE represents the potential energy of the spring. - k is the spring constant, which represents the stiffness of the spring. - x is the displacement or extension of the spring from its equilibrium position.

2. Potential Energy of a Compressed Spring: - When a spring is compressed, the potential energy can also be calculated using the formula: PE = (1/2)kx^2. - PE represents the potential energy of the spring. - k is the spring constant, which represents the stiffness of the spring. - x is the displacement or compression of the spring from its equilibrium position.

It's important to note that the potential energy of a deformed spring is directly proportional to the square of the displacement or deformation from its equilibrium position.

Let's solve an example problem to illustrate the calculation of potential energy for a deformed spring.

Example: Suppose we have a spring with a spring constant of 100 N/m and it is stretched by 0.1 meters. We can calculate the potential energy using the formula:

PE = (1/2)kx^2

Substituting the given values: PE = (1/2)(100 N/m)(0.1 m)^2 PE = 0.5 N*m = 0.5 Joules

Therefore, the potential energy of the deformed spring is 0.5 Joules.
