Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An object that has momentum can be described as ____
A
changing its velocity
B
moving fast
C
resisting changes in its state of motion
D
having its mass in motion
E
encountering a net force
Explanation: 

Detailed explanation-1: -Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum-it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving.

Detailed explanation-2: -An object with mass will have momentum. An object which is moving at a constant speed has momentum. An object can be traveling eastward and slowing down; its momentum is westward. Momentum is a conserved quantity; the momentum of an object is never changed.

Detailed explanation-3: -Momentum is the quantity that is used to describe the state of motion of an object with a non-zero mass. Hence, momentum is applicable to any moving object. If is the mass of an object and is the velocity with which this body travels, then momentum can be expressed as p → = m v → .

Detailed explanation-4: -Momentum is the quantity of motion that is multiplied by the amount of matter moved and the velocity at which it moves. Because the object is in motion, it is a vector quantity. It is determined by the product of the object’s mass and velocity.

Detailed explanation-5: -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.
