Question
Find the potential energy if the body has a mass of 1 kg and no height.
- 1J
- 2J
- 0J
- None
Hint:
Potential energy= mass x gravitational acceleration x height.
The correct answer is: 0J
Given,
mass of the object = 1 Kg
Height from which the object is falling = 0 m
According to the formula,
Potential energy= mass x gravitational acceleration x height.
PE = 1 x 9.8 x 0 ( gravitational acceleration = 9.8m/s2)
PE = 0 J
