1️⃣First law:
Ex.
✔️Passenger sitting in a bus falls backward when the bus starts suddenly because of the inertia of rest. Again, when bus stops suddenly passenger falls forward because of inertia of motion.
2️⃣Second law:
Ex.
✔️The motion of a cricket ball after being hit by a bat, pushing a car to start the engine, objects falling under gravity etc. The difficulty you face while pushing or pulling a heavier box compared to a lighter box is explained by the 2ndlaw of motion.
3️⃣Third law:
Ex.
✔️When you stand on the ground, your weight pushes the ground downwards and the ground pushes you upward with a force equal to your weight and hence these equal and opposite forces cancel out and you stand on the ground balanced. Force by you on the ground and force on you by the ground are two equal and opposite forces acting in pairs at the surface that is common to both you and the ground.

1. The body in a train goes backward when the train suddenly starts.
2.While catching a cricket ball the momentum of ball is reduced to zero when it is stopped after coming in the hands of fielder. If the ball is stopped suddenly, its momentum will be reduced to zero instantly. The rate of change in momentum is very quick and as a result, the player’s hand may get injured. Therefore, by pulling the hand backward a fielder gives more time to the change of momentum to become zero. This prevents the hands of fielder from getting hurt.
3. Shooting a bullet from a gun.
