Question

Wacky scientist Jumpy Jane puts spring on her shoes and bounces up and down in simple harmonic motion. The total mechanical energy of Jane's system is:

1. a non-zero constant.

2. a minimum when it passes through the equilibrium point.

3. zero as it passes the equilibrium point.

4. a maximum when it passes through the equilibrium point.

5. zero when it reaches the maximum displacement.

Answer 1

Mechanical energy = kinetic energy + potential energy

Mechanical energy remains constant because kinetic energy and potential energy converted into each other.

So mechanical energy remains constant.

Option 1 is correct.

A Non zero constant
