Question 57

Elastic potential energy is the type of energy stored in a compressed spring.

When a spring is compressed, it stores energy due to its position, which is known as elastic potential energy. This energy is released when the spring returns to its original shape.

A) Elastic potential energy

This option is correct because elastic potential energy is the energy stored in an object when it is deformed, such as when a spring is compressed or stretched. The energy is dependent on the amount of compression or extension from its equilibrium position.

B) Thermal energy

This option is incorrect as thermal energy refers to the internal energy present in a system due to its temperature. It is not related to the mechanical deformation of a spring, hence does not apply to the situation of a compressed spring.

C) Electromagnetic energy

This option is also incorrect because electromagnetic energy pertains to energy carried by electromagnetic waves, such as light or radio waves. It does not relate to the mechanical energy stored in a spring.

D) Kinetic energy

This option is incorrect as kinetic energy is the energy of an object due to its motion. A compressed spring does not have kinetic energy until it is released and begins to move, thus it does not apply to the energy stored in a compressed spring.

Conclusion

Elastic potential energy is the only option that accurately describes the energy stored in a compressed spring, as it is directly related to the deformation of the spring. The other options do not pertain to the mechanical energy associated with the compression of a spring, making them incorrect in this context.
