Detailed Solution

The above statement is True.
In mechanics, momentum is defined as the product of the mass of an object and its velocity. It is a vector quantity that has a magnitude and direction as well.
If ‘

m

’ is the mass of the object and ‘

v

’ be its velocity, then the momentum of the object is given by

p = mv

Its SI Unit is given by

kg . m / s

N - s

.
Momentum is a vector quantity; that is, it has both magnitudes as well as directions. Since mass is a scalar and velocity is a vector quantity, a product of a scalar and a vector quantity provides an overall vector quantity. Newton’s second law of motion states that the rate of change of momentum is directly proportional to the force applied to an object.
