Can any object have mechanical energy even ifits momentum is zero? Explain. |

Answer» An objectthat possessesmechanical energyis able todowork. In fact,mechanical energyis often defined as the ability todowork. Any objectthat possessesmechanical energy- whether it is in the form of potential energyor kineticenergy- is able todowork. Momentumis the product of mass and velocity of a body, for a body mass never bezerobut velocitycanbezero ifa body is at rest, Soifa body is at restits momentum is zerobutif it isin rest at a height it possesses gravitational potentialenergyhencemechanical energy.
