Given what we know, we can confirm that the change in kinetic energy is a negative value, given that the final value 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, it no longer has kinetic energy.
Given that the change in kinetic energy is the final value minus the initial, 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.
