Question

Verify the principle of conservation of mechanical energy taking example of freely falling body​

Answer 1

Answer:

If a body of mass m is in motion with speed v, then its kinetic energy is equal to K=12mv2. Let us now prove the conservation of the mechanical energy during a body falling freely. ... Hence, its kinetic energy will be K2=12mv2 and change in kinetic energy (ΔU) will be K2=12mv2.

Answer 2

If a body of mass m is in motion with speed v, then its kinetic energy is equal to K=12mv2. Let us now prove the conservation of the mechanical energy during a body falling freely. Hence, its kinetic energy will be K2=12mv2 and change in kinetic energy (ΔU) will be K2=12mv2.
