The correct answer is: Momentum.
Momentum is a vector quantity that is defined as the product of the mass and velocity of an object. It is a measure of the object’s inertia and its ability to resist changes in its motion. Momentum is conserved, which means that the total momentum of a system remains constant unless an external force acts on the system.
Momentum is often used in physics to calculate the motion of objects. For example, the momentum of a moving object can be used to calculate its kinetic energy, which is the energy of motion. Momentum can also be used to calculate the force required to stop an object.
The other options are incorrect because they do not accurately describe the product of mass and velocity.
- Moment is a measure of the tendency of a force to produce rotation. It is not the product of mass and velocity.
- Power is the rate at which work is done. It is not the product of mass and velocity.
- Impulse is the change in momentum of an object. It is not the product of mass and velocity.
