Question

Which of the following energy conversions is depicted in the figure given below?

• A. Kinetic energy of the spring is converted into potential energy of the ball.
• B. Potential energy of the spring is converted into kinetic energy of the ball.
• C. Kinetic energy of the ball is converted into potential energy of the spring.
• D. Potential energy of the ball is converted into kinetic energy of the spring.

Answer 1

The correct option is B

Potential energy of the spring is converted into kinetic energy of the ball.

Initially the spring is in its natural length. It is then compressed by applying a force because of which it gains potential energy. Upon being released, the potential energy stored in the compressed spring is converted into kinetic energy of the ball.
