Question

can any object have mechanical energy even if the momentum is 0?​

Answer 1

Answer:

Yes.

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.

Answer 2

Answer:

yes

Explanation:

the body can have because potential energy is acting
