Explanation:
Detailed explanation-1: -Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.
Detailed explanation-2: -This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
Detailed explanation-3: -A slow moving car may have more kinetic energy than a fast moving motorcycle. How is this possible? Logic – the slow moving car has a large mass, which contributes to its Kinetic Energy.
