Answer 2

$\red{ \bf{ \rm{\underline{Newton's \: \: First \: \: Law \: \: of \: \: \blue{\mathbb{ MOTION}}}}}}$

" Every object which is at rest or uniform motion continues to be in state of res or uniform motion unless compelled to change its state by action of net force."

Example

• When you shake a branch the leaves get detached.
• Experiencing jérk when lift suddenly starts.

$\red{ \bf{ \rm{\underline{Newton's \: \: Second \: \: Law \: \: of \: \: \blue{\mathbb{ MOTION}}}}}}$

" Rate of change of momentum of the body is directly proportional to the force acting on it."

Example

• Player in a cricket match pulls his hand backwards to reduce impact of impulse force
• Working of air bags to prevent the time of injury.

$\red{ \bf{ \rm{\underline{Newton's \: \: Third \: \: Law \: \: of \: \: \blue{\mathbb{ MOTION}}}}}}$

" For every action there is equal and opposite reaction "

Example

• Working Principle of Rocket.
• Recoil of a gun
