The meaning of MOMENTUM is a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity; broadly : a property of a moving body that determines the length of time required to bring it to rest when under the action of a constant force or moment.
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
Jul 28, 2023 · Momentum is a quantity involving the motion of an object. Objects with greater mass naturally have high momentum, but this will also depend on velocity. Suppose a car and a truck move on the highway with the same velocity. Both have momentum. The truck is heavier than the car, so it will have higher momentum.
Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. Momentum = mass • velocity. In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as. p = m • v
Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

If an object is moving, its momentum cannot be zero. However, this is not necessarily true for a system. Since momentum is a vector, the total momentum of a system can be zero if there are multiple masses.
But momentum takes into account magnitude and direction. Furthermore, momentum is not only caused by velocity but also mass. An object can travel at a very high velocity but still can have a very small momentum, maybe because of its small weight. In addition, momentum can be negative (it takes direction into account) unlike speed.
A vector quantity that expresses the relation of the velocity of a body, wave, field, or other physical system, to its energy. The direction of the momentum of a single object indicates the direction of its motion.
