Due a decrease in the velocity of the cart, the change in kinetic energy is negative

What is kinetic energy?

Kinetic energy is the energy of a body due to its motion.

  • The change in kinetic energy is positive if the mass of a body or the velocity of the body increases.
  • The change in kinetic energy is negative if the mass of a body or the velocity of the body decreases.
  • The change in kinetic energy is zero if the mass of a body or the velocity of the body remains constant.

Since the cart is slowed down, its velocity decreases and the change in kinetic energy is negative.

In conclusion, the change in kinetic energy of a body is affected by the mass and velocity of the body.
