Question

Kinetic energy and mass are related as

  1. KE space proportional to space straight m
  2. KE space proportional to space 1 over straight m
  3. KE space proportional to space straight m squared
  4. KE space proportional to space 1 over straight m squared

hintHint:

K directly proportional m

The correct answer is: KE space proportional to space straight m


    Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.
    K.E. = 1/2mv2
