Question

what is the momentum of a body of mass 'm' moving with velocity'v'?​

Answer 1

Momentum of body with mass 'm' and velocity 'v' is mv.

Momentum = mass × velocity

Momentum is the helper of force you can say. The strength of force that keeps the body moving or at rest.

Answer 2

Answer:

The momentum of a body of mass 'm' moving with velocity 'v' is mv.

Explanation:

• Momentum or linear momentum is defined as the product of the mass and velocity of a body. Since the mass and the velocity are vector quantities, it is also a vector quantity.
• Momentum can be explained in terms of the motion.
• In any closed system (where there is no change in mass), where the value of external forces is zero, the momentum is conserved. This means to say the value of momentum before the collision of bodies is equal to the momentum after the collision of the same bodies.

       Mathematically, it can be written as,

                    m₁  v₁        =        m₂  v₂

          (before the collision)        (after collision)

• The momentum of a body increases on either increase of the mass or the velocity. Suppose a body of mass 'm' is moving with velocity 'v', and the momentum (р) of a body is calculated as,

                 momentum=mass × velocity

                               ⇒р=mv

Thus, the momentum produced in a body will be 'mv'.
