Can Kinetic Energy Be Negative?
Answer – Kinetic energy cannot be negative.
Explanation:
Kinetic energy is the energy of motion. It is a property of a moving object or particle and depends not only on its motion but also on its mass.
The equation for kinetic energy, KE=1/2mv2 ensures that kinetic energy remains positive or zero. This is because the mass (m) is always positive, and even if the velocity (v) is negative, it becomes positive when squared, resulting in a non-negative value for kinetic energy.
