Third law of motion examples in daily life

Examples of newton’s laws in everyday life based on third law of motion:

•Our hand feels pain when we hit the table because the table gives force as a reaction to our hand

•When someone swim, force given from his hand to the water results a reacting force from the water with the total force as big as his hand’s force, but in the opposite direction. So that he moves forward even though he swing his hand backward

•Another example is that when we throw a ball upward, force of gravity is applied by the earth on the ball. Ball follows the projectile motion and accelerates towards the earth due to the force of gravity applied by the earth on the ball. In the similar fashion, ball also applies same force to the earth and tries to attract the earth towards it. But the earth mass is very large, so the acceleration produced in the ball is very small or negligible.

•fmForce exerted by the hammer on the nail is Fhn and the force exerted by the nail on the hammer is shown by Fnh. Here the force exerted by the hammer on the nail is equal in magnitude and opposite in direction to the force applied by the nail on the hammer.

•Suppose a person slams the wall with his fist. The force applied by the person through his fist on the wall is equal to the force applied by the wall on the fist. Harder the person slams the wall, more he gets hurt. Similar procedure is followed when a person kicks the football.

•When we touch the rock with toe and apply force on it, the toe exerts force on the rock. Equal amount of force is exerted back on the toe by the rock. If you apply more force on the rock by the toe, more force is felt by you and it hurts.

•When rocket moves in the space it pushes the gas outside from it, i.e., rocket applies force on the gases in the backward direction. As a reaction, the gases put equal amount of force on the rocket in the opposite direction and the rocket moves in the forward direction.
