Question

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

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. Yes

Answer 2

Answer:

if momentum is zero then energy is also zero

Explanation:

This is because momentum =mv2 square.if momentum is zero.thats means velocity is zero.because mass never zero.

Energy =half mv square. it means energy also depends on velocity

so velocity is zero then energy is zero.

Therefore energy is also zero when momentum is zero.

Thanku.
