Question

Kinetic energy and velocity are related as

  1. K E space proportional to space v squared
  2. KE space proportional to space 1 over straight V squared
  3. KE space proportional to space straight v
  4. KE space proportional to 1 over straight v squared

Hint:

KE is directly proportional to v²

The correct answer is: K E space proportional to space v squared


    Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.
