Question

A weight is connected to a spring that is suspended vertically from the ceiling. If the weight is displaced downward from its equilibrium position and released, it will oscillate up and down.

If air resistance is neglected, will the total mechanical energy of the system (weight plus Earth plus spring) be conserved?

A. Yes
B. No

Answer 1

Yes

Step-by-step explanation:

Neglecting air resistance, the total mechanical energy of the system would be conserved because the two forces acting on the weight are the spring force and the gravitational force, and both are conservative in nature.
