Question

Can kinetic energy be negative? Explain.

Answer 1

Kinetic Energy cannot be negative

Step-by-step explanation:

KE = 1/2 mass • velocity^2

All mass has a positive value and the velocity squared is positive

Answer 2

Although the kinetic energy depends on the speed and this can be negative due to the direction in which it points according to the convention, the equation of the kinetic energy is:

E = 0.5*m*V²

The fact that the speed is squared tells us that any value of negative speed will become positive and mass is always positive, so it follows that kinetic energy cannot be negative.
