Question

Which type of force, when acting alone, leads to the decrease in potential energy being entirely converted into kinetic energy?

Options

• Only conservative forces.

• Only opposing/retarding forces.

• Non-conservative forces.

• Both conservative and non-conservative forces.

Answer 1

Only conservative forces.

Explantion:

The Work-Energy Theorem in this form specifically applies to conservative forces, where mechanical energy is conserved and conversion is complete.
