A body of mass 1 kg is lifted through a height of 1 m. The energy possessed in the body will be: (consider g = 10 ms^-2).
Answer: 10 Joule
Explanation
The potential energy (PE) of an object is calculated as:
PE = mass x gravity x height
= 1 kg x 10 m/s^2 x 1 m
= 10 Joule
So, the energy possessed by the body is 10 Joule.
