Question

A spring of spring constant 2 N/m is compressed by 1m. Which is a more meaningful statement.

• A. The change in potential energy is 1J.
• B. The kinetic energy of the spring is 1J
• C. The spring has no energy
• D. The potential energy of the spring is 1J.

Answer 1

The correct option is A The change in potential energy is 1J.

The change in potential energy is 1J. We can associate any number to its energy when it is at its natural length.
