Question

Calculate the potential energy of a body of mass 5 kg at height of 2 m from the ground

Open in App

Solution

potential energy=P.E
PE = mgh
where m is mass of the body , g is acceleration due to gravity , h is the height above the ground.
• For 5Kg body :
PE at 2m height above the ground is given by = 5×9.8×2=98J
