A fast-moving object has more kinetic energy compared to a slow-moving object of the same mass because kinetic energy is directly proportional to the square of the object’s velocity. This means that even a small increase in velocity results in a significantly larger increase in kinetic energy. The formula for kinetic energy is:
K E = 1/2mv²
Thus, if the velocity of an object doubles, its kinetic energy increases by a factor of four.
Why does a fast-moving object have more energy compared to a slow-moving object of the same mass?

A fast-moving object has more energy than a slow-moving object of the same mass because kinetic energy depends on the square of the velocity. Given by the formula K E = 1/2mv² , doubling the velocity quadruples the kinetic energy, thus making a fast-moving object significantly more energetic.
