Question:
Which of the following types of energy is possessed by a compressed spring?
Which of the following types of energy is possessed by a compressed spring?
Show Hint
Any elastically deformed solid body (like a compressed spring or a bent beam) stores mechanical energy in the form of strain energy, calculated as $U = \frac{1}{2} k x^2$.
Updated On: Aug 7, 2026
- Kinetic energy
- Kinematic energy
- Retaliation energy
- Strain energy
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
When a material is deformed elastically by an applied force, work is done on the material.
This work is stored internally as potential energy, which is released when the material returns to its original shape.
Step 2: Detailed Explanation:
A spring is an elastic component designed to undergo deformation under load.
When a spring is compressed or stretched, the work done against its internal elastic forces is stored within the spring.
In engineering and solid mechanics, this stored elastic potential energy is known as Strain energy.
- Kinetic energy is the energy possessed by an object due to its motion ($KE = \frac{1}{2}mv^2$).
- Kinematic energy is not a recognized thermodynamic or mechanical category of energy.
- Retaliation energy is not a scientific term in mechanics.
Therefore, a compressed spring possesses strain energy (elastic potential energy).
Step 3: Final Answer
The correct option is (D).
