0.1 J of elastic potential energy will be stored by the spring when it gets compressed by 0.2 m if it has the spring constant of 5 N/m.
Elastic potential energy can be defined as the potential energy stored by the spring when it is stretched or compressed.
- Amount of energy stored in the elastic material or spring is directly proportional to the amount of compression or elongation.
- It is represented by U.
- Mathematically, U =
; k is the spring constant and x is the compression or expansion suffered by the spring
According to the question.
Compression in the spring, x = 0.2 m
Spring constant, k = 5 n/m
Elastic potential Energy, U =
U = 0.1 J
0.1 J of elastic potential energy will be stored by the spring.
