Question

An object og mass 20kg is dropped from a heigh of 4m.Calcualte potential energy ,Kinetic energy and mechanical energy

Open in App

Solution

Mass = 20 kg
Total Enegry = mgh = 20 10 4= 800J = mechanical energy
Kinetic energy = 0
so this is the total energy if you calculate Kinetic energy and potential energy at any point in b/w there sum will be equal to the mechanical energy.
