Question:
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.
Solution:
Momentum, $\vec{p}=$ mass $(m) \times$ velocity $(\vec{v})=m \vec{v}$
SI unit of $\vec{p}$ is $\mathrm{kg} \mathrm{m} \mathrm{s}^{-1} . \mathrm{F}=\frac{d p}{d t}$
