Question

Can a body possess mechanical energy even if it's momentum is zero?? How??

Answer 1

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.

Answer 2

momentum is product of mass and velocity of body .....for a body mass cannot never be zeroo but it can be for velocity if body is at rest
