why is it so?

applicable.

Answer:
Newton's first law:
1)Two people are made to run a certain distance say 50 metres , then a mark was kept in the middle say at 25 mts, after a few laps the students are made to stop suddenly at the midway spot, it can be seen that even after stopping the upper body of the two people seems to be keep moving , this is due to the inertia of motion.
2)If we keep a glass at rest on a cloth over a table and we remove the cloth quickly, we will see that the glass will remain at rest. This is due to inertia of rest.
3)A ball if thrown in outer space without gravity will keep on going till eternity unless it meets a resistance of force.
Newton's second law:
4)There are two vehicles one car and a loaded truck, the car is pushed with a certain force and the same is exerted on the loaded truck , we will see that the car will accelerate faster than the truck.
5)When we are using a shopping cart , the empty shopping cart will move faster than a filled one because mass is inversely related to force.
6)An empty sofa is easy to move than a sofa with people sitting on it.
Newton's third law :
7)Gun when fired exerts a force on the bullet and the same but opposing force is seen during the recoiling of the gun.
8)An archer when shoots an arrow, he pulls the arrow on the string with a certain amount of force, this same but opposing force which helps the arrow to fly faster.
9)Rowing of boat is an example of third law of motion because as we row the boat in an opposite direction , we move forward.
10)If we put a hole at the bottom a balloon filled with air, it will start to rise higher because of the opposite force that is exerted on the balloon.
