Question

What are the SI units of momentum?

Answer 1

Hint: Momentum can be stated as "mass in motion." All bodies have mass, so if a body moves, it has its mass in motion. The momentum of an object has depended on two variables: how much material is traveling and how fast it moves. In terms of the equation, the momentum is equal to the body's mass times its velocity.

Complete answer:
The momentum of the object is the mass of an object multiplied by the velocity of an object. It has a magnitude and a direction. It is a vector quantity.
$p = m \times v$
where m is the mass of the object.
v is the velocity of an object.
The SI unit of the mass is Kilogram (Kg) and the SI unit of the velocity is $ms^{-1}$ .
The SI unit of the momentum is $Kg ms^{-1}$.
Newton's second law of motion describes that the rate of change of a body's momentum is equal to the total force acting on it.
$F = \dfrac{dp}{dt}$
$\implies dp = F \times dt$
The SI unit of the Force is Newton (N) and the SI unit of the time is second (s).
The SI unit of the momentum is .
Hence, the SI unit of the momentum areand $Kg ms^{-1}$.

Additional Information:
The law of conservation of momentum defines that the total momenta of two bodies before and after the collision, remains identical given that no outside unbalanced force performs upon them. Differently, collision maintains the total momentum of two bodies.

Note:
Momentum depends upon the mass and velocity. Momentum is a quality of a body that the body has its mass, and motion is equal to the multiply of the mass of the body and velocity, and it also determines the time period needed to bring it to a stationary state under the effect of a steady force.
