When a moving car comes to a stop, what happens to its kinetic energy?
It becomes zero
The kinetic energy of a body of mass m moving with velocity v is given by KE = ½mv², which clearly shows that kinetic energy depends on the square of the speed.
When a moving car gradually slows down and finally comes to rest, its velocity reduces to zero, so substituting v = 0 into the formula gives KE = ½ × m × 0² = 0.
The energy the car once possessed is not destroyed; it is converted into other forms such as heat and sound through friction and braking, but the kinetic energy of the car itself becomes zero.
Hence, the correct answer is It becomes zero.
