Question

What is the combined effect of mass and velocity that is taken into account by a physical quantity called-
(A) Torque
(B) Moment of Force
(C) Momentum
(D) Moment of momentum

Answer 1

Hint
Velocity defines the direction of the movement of the body or the object. Velocity is the prime indicator of the position as well as the rapidity of the object. It can be defined as the distance covered by an object in unit time. Velocity can be defined as the displacement of the object in unit time.

Complete step by step answer
As we know that the product of mass (kg) and velocity (m/s) is called momentum (kg/ms). it is also directly proportional because if the mass changes that the momentum will change if the velocity changes, so we can say that is also directly proportional. Mass and velocity both are considered to be quantities which defines motion.The combination of both is called quantity of motion.It is momentum.
$P=mv.$
Option (C) is correct answer.

Note
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
