Is it possible for the total mechanical energy of a moving particle to be negative?
A) No, because a moving particle has positive kinetic energy.
B) No, because potential energy cannot have a value more negative than the value of the positive kinetic energy of the particle.
C) Only if friction is involved.
D) Yes

Question

Quizplus · Accepted Answer

The total mechanical energy of a particle is the sum of its kinetic and potential energies. While kinetic energy is always positive, potential energy can be negative. If the negative potential energy is greater in magnitude than the positive kinetic energy, the total mechanical energy can be negative.
