Question

Can any object have machnical energy even if it’s momentum is zero. Explain.

Answer 1

Explanation:

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. Mechanical energy includes gravitational potential energy

Answer 2

Answer:

Yes, a body can have mechanical energy even if it's momentum is zero. For example, the body at a height "h" will have potential energy (mgh) . The body is stopped and hence has zero kinetic energy (hence 0 momentum)

Still it has mechanical energy (potential energy).
