Question

When a stretched rubber band is released, its stored potential energy is converted into which form of energy?

This question was previously asked in
RRB NTPC 2025 Graduate CBT 2 Question Paper PDF (10-Jul-2026) (Shift 1)
The correct answer is

Kinetic Energy

A stretched rubber band stores elastic potential energy, which converts into kinetic energy of motion once released.

Hydraulic, chemical and geothermal energy describe entirely different energy sources, unrelated to a released elastic band.

Hence, Kinetic Energy is the correct answer.
