Question

As mass decreases, kinetic energy

  1. Increases
  2. Decreases
  3. Remains same
  4. Varies exponentially

hintHint:

Decreases

The correct answer is: Decreases


    Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. Hence, when mass decreases kinetic energy also decreases.
