Question
Find the potential energy of a body if a body of mass 10 kg is falling from a height of 10 m.
- 900J
- 950J
- 980J
- 1000J
Hint:
Potential energy= mass x gravitational acceleration x height.
The correct answer is: 980J
Given,
mass of the object = 10 Kg
Height from which the object is falling = 10 m
According to the formula,
Potential energy= mass x gravitational acceleration x height.
PE = 10 x 9.8 x 10 ( gravitational acceleration = 9.8m/s2)
PE = 980J
