Given what we know, we can confirm that the change in kinetic energy is a negative value, given that the <u>final value </u>will be zero.

<h3>What is kinetic energy?</h3>
  • This is the energy of movement.
  • As the car is in motion, it has kinetic energy.
  • However, as the car slows down, it loses this energy.
  • Once the car stops,<em><u> it no longer has kinetic energy. </u></em>
  • Given that the change in kinetic energy is the <em><u>final value </u></em>minus the <em><u>initial</u></em>, and the final is zero, this will cause the change in kinetic energy for the car to be a negative value.

Therefore, since kinetic energy is the energy of movement, we can confirm that the change in kinetic energy for the car will be a negative value caused by the car coming to a complete stop.
