What is momentum? Write its SI unit. Interpret force in terms of momentum. Represent the following graphically
$(a)$. momentum versus velocity when mass is fixed.
$(b)$. momentum versus mass when velocity is constant.

Momentum is a property of a moving body which is the virtue of both its mass and velocity. Momentum is the product of the mass and velocity of a moving body.


Here, $P\rightarrow$ momentum

$m\rightarrow$ mass

$v\rightarrow$ velocity

The SI unit of momentum is Kilogram-meter/ second$(kg-m/s)$.

$(a)$. momentum versus velocity graph when mass is fixed:

$(b)$. momentum versus mass graph when velocity is constant:
