Solution

## Definition:Momentum seems to be the proportion of motion of a moving object. It is calculated by multiplying the mass by velocity.The SI unit of momentum is $\mathrm{kg}\mathrm{m}{\mathrm{s}}^{-1}$.Formula: $\mathrm{Momentum}=\mathrm{mass}×\mathrm{velocity}$Force in terms of momentum is $\text{Force=Rateofchangeinmomentum}$Momentum versus velocity when mass is fixed.$\mathrm{P}=\mathrm{mv}$When m is constant momentum will be directly proportional to velocity. Step 3: Momentum versus mass when velocity is constant.$\mathrm{P}=\mathrm{mv}$When v is constant momentum will be directly proportional to mass.   Suggest Corrections  44      Similar questions
