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

Answer

Momentum is measured as product of mass and velocity.
Momentum \(=\) mass \(×\) velocity
\(p=m (kg)\times v(ms^{-1})\)
\(SI\) unit of momentum is \(kg\ m\ s^{-1}\)
Force is defined as rate of change of momentum. Let an object of mass \(m\) move with initial velocity \(u\) and after some time the velocity changes to \(v\). Thus \(F=mv-mu\)
\(F=p_2-p_1\)
The graph between momentum and velocity is shown below. When \(m\) is fixed, momentum is given as \(p\propto v\).
