Question

what is meant by momentum ?

Answer 1

Answer:

Definition of momentum

1 : a property (see property sense 1a) of a moving body that the body has by virtue of its mass (see mass entry 2 sense 1c) 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

2 : strength or force gained by motion or by a series of events The wagon gained momentum as it rolled down the hill.

• Momentum is a vector quantity that is the product of the mass and the velocity of an object or particle. The standard unit of momentum magnitude is the kilogram-meter per second (kg · m/s or kg · m · s -1 ). Alternatively, the gram-centimeter per second (g · cm/s or g · cm · s -1 ) can be used to express momentum magnitude. The direction of a momentum vector can be expressed in various ways, depending on the number of dimensions involved, and is the same as the direction of the velocity vector.

• 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. See Newton's laws of motion. Momentum.

There are two kinds of momentum, linear and angular.
