Question

Find the potential energy of the body if the mass of the object is 1 kg and have a height of 1 m.

  1. 0.2J
  2. 1J
  3. 9.8J
  4. 2J

hintHint:

  Potential energy= mass x gravitational acceleration x height.

The correct answer is: 9.8J


    Given, 
    mass of the object = 1 Kg
    Height from which the object is falling = 1 m
    According to the formula,
      Potential energy= mass x gravitational acceleration x height.
    PE = 1 x 9.8 x 1  ( gravitational acceleration = 9.8m/s2)
    PE = 9.8 J
