s it possible for a system to have negative potential energy? Is it possible for a system to have negative potential energy? No, because the kinetic energy of a system must equal its potential energy. Yes, as long as the total energy is positive. Yes, since the choice of the zero of potential energy is arbitrary. No, because this would have no physical meaning. Yes, as long as the kinetic energy is positive.

Answer: Yes it possible for a system to have negative potential energy, since the choice of the zero of potential energy is arbitrary.

Explanation:

Potential energy is defined as the energy present in an object due to its position.

Mathematically, P. E = mgh

A potential energy can be negative also. This is because zero potential energy is arbitrary. For example, at the top of a building the choice of potential energy can be zero.

Therefore, the potential energy below the building will be negative.
