Hi frnd,
Newton's First Law states that " 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:A space creft far from any source of gravity would need no thrust to keep it moving at a constant speed in a given direction.Once set in motion, it continues to move forever without propulsion since there is no frcition is space.
Second law of motion " Rate of change of momentum of the body is directly proportional to the force acting on it."
Example:Fielder in a cricket match pulls his hand backwards to reduce impact of impulse force.Working of air bags to prevent the time of injury.
Third law of motion states " For every action there is equal and opposite reaction "
Example:Working Principle of Rocket.Recoil of a gun.
1st law: fans dont stop even when the force is removed
2nd law: Trucks have more powerful wngines than car
3rd law: As you sit in your chair, your body acts on the chair with one force, and the chair reacts on your body with yet another force.
Hope this helps bro
