Question
Find the potential energy if the body has a mass of 2 kg and is falling from 10 m.
- 190J
- 195J
- 196J
- 199J
Hint:
Potential energy= mass x gravitational acceleration x height.
The correct answer is: 196J
Given,
mass of the object = 2 Kg
Height from which the object is falling = 10m
According to the formula,
Potential energy= mass x gravitational acceleration x height.
PE = 2 x 9.8 x 10 ( gravitational acceleration = 9.8m/s2)
PE = 196J
