why does potential energy increase as we go up conceptually not with formula=mgh and please explain potential energy?
Now if you are climbing the steps.You are doing work against gravitational force.
Now you need more amount of energy compare to gravitational force.
Potential energy is energy require to do certain work.
Hence as you go up that much amount of energy is spent and its stored as potential energy(your ability to go up). Potential energy is a measure of work done overcoming the force of gravity, so the higher you go the more energy you need.
