Can any object have mechanical energy even if its momentum is zero? Explain.
Answer :
Yes, Objects have mechanical energy even if its momentum is zero. Mechanical energy is sum of both potential energy and kinetic energy.
Momentum = mv = 0 ∴ v=o since m can never be zero.
Hence, there is no kinetic energy but the object may possess potential energy. Since PE is the product of mass, gravitational constant and height
