Linear Momentum
  1. Linear momentum of a body is the quantity of motion contained in the body.

  2. It is measured in terms of the force required to stop the body in unit time.

  3. If a body of mass m is moving with velocity \vec{v}, then its linear momentum \vec{p} is given by \vec{p}=m\vec{v}.

  4. It is a vector quantity and its direction is the same as the direction of the velocity of the body.

  5. S.I. Unit : kg-m/sec

  6. Dimension- MLT-1

  7. If two objects of different masses have the same momentum, the lighter body possesses greater velocity. 

               As p=m1v1=m2v2=constant

                 \therefore \frac{V_1}{V_2}=\frac{m_2}{m_1}\Rightarrow V \ \alpha \ \frac{1}{m}
