Question
State the impulse-momentum theorem.
✓
Answer
Impulse of a force is equal to change in momentum due to that force. This is called impulse momentum theroem. According this theorem is the change in momentum of an object is constant then its impulse will also be constant. $\overrightarrow{J}=\left(\overrightarrow{P_2}-\overrightarrow{P_1}\right) $ That is, if the forces $\vec{F}_1$ and $\vec{F}_2$ are applied to produce the same impulse of an object for time $t_1$ and $t_2$ respectively then, $\overrightarrow{F_1} t_1=\overrightarrow{F_2} t_2$
