Question

2. Conduct an experiment to calculate the total energy of a freely falling body at different heights.​

Answer 1

1) At a potential Energy = mgh. kinetic energy = 1/2 mv² = 1/2 × m × 0 kinetic energy = 0. The velocity is zero as the object is initially at rest

2) At B, potential energy = mgh = mg(h - x) [Height from the ground is (h-x)] potential energy =mgh - mgx

3) At C, potential energy { m× g × 0 ) ( h = 0 )
