Question

14. Can any object have mechanical energy even if its momentum is zero? Explain.​

Answer 1

Answer:

Momentum of a body is equal to the product of its mass and velocity. ... So the kinetic energy of a body is equal to zero equals zero. But it may have potential energy. So, even if the momentum of the body is zero, it may have mechanical energy.

Answer 2

Answer:

Momentum is the product of mass and velocity of a body, for a body mass never be zero but velocity can be zero if a body is at rest, So if a body is at rest its momentum is zero but if it is in rest at a height it possesses gravitational potential energy hence mechanical energy. Yes.
