The kinetic energy of an object increases with its _____.
Show answer & explanation
Correct answer: A
Explanation
Kinetic energy is the energy possessed by an object by virtue of its motion. According to physics, the formula for kinetic energy is KE = 1/2mv², where 'm' represents mass and 'v' represents velocity. It is evident from this formula that kinetic energy is directly proportional to the square of the object's velocity. Therefore, when the speed of an object increases, its kinetic energy also increases. For instance, a car moving at high speed possesses greater kinetic energy compared to a slow-moving car.
