Detailed explanation-1: -To meet the definition of having momentum, an object must be moving. Momentum is mass in motion. To have momentum an object (which is guaranteed to have mass) must be moving.
Detailed explanation-2: -It is the product of an object’s mass and velocity. An object at rest has a momentum of 0. This helps distinguish momentum from inertia. An object must be in MOTION to have momentum.
Detailed explanation-3: -In order to have momentum, an object must be in motion. All objects that are moving have momentum, but objects that are not in motion have no momentum.
Detailed explanation-4: -ANSWER: FALSE-An object has momentum if it is moving. Having mass gives an object inertia. When that inertia is in motion, the object has momentum. If an object does not have momentum, then it definitely does not have mechanical energy either.
