5 examples for the law of action reaction

5 examples for the law of inertia

5 examples for law of force

i)ACTION AND REACTION

1)When a bullet is fired from a gun the gun exerts a force on the bullet causing it to move forward . The bullet exerts an equal and opposite force causing the recoil of the gun.

2)When a person swims , he moves his hands underwater which exerts a force on opposite direction of his motion and causes him to swim forward since the water exerts a similar force on the person.

3)when a rocket is launched , a force is exerted by it on the ground causing it move upwards as an equal and opposite force acts on it.

4)when we jump off a boat we exert force on the boat causing it to move on water away from the land.

5)when we fall on a cement floor we exert a force on the floor and the floor exerts a similar force on us causing us to injure.

ii)LAW OF INERTIA

1)when a bus at rest starts suddenly,the passengers in it tends to fall backwards because the upper part of the body tends to remain at rest due to inertia of rest.

2)when a fast moving bus stops suddenly,the passengers in it tends to fall forward because the upper part of the body tends to remain inmotion due to the inertia of motion.

3)when a fast moving bus turns along a curve in a road,the passengers tend to fall on the other side because the upper part of the body tends to remain in the same direction due to the inertia of direction.

4)when we beat a carpet full of dust from a certain height,the dust particles tends to remain at rest and therefore falls off from the carpet due to the gravitational force and inertia of rest of the dust particles.

5)when we shake a tree branch the leaves tend to remain at rest due to inertia of rest.in this situation the leaves lose contact with the branch and falls down due to gravity.

iii)LAW OF FORCE/SECOND LAW OF MOTION

1)when a cricket player catches a ball , he lowers his hands to increase the time taken to catch the ball therefore reducing the force exerted on his hands.

2)a karate person breaks a pile of bricks very quickly to decrease the time taken to apply the force thus increasing the force.

3)the children;s park is covered full of sand because when any child falls , they go into the sand causing the time to increase and force exerted on the falling child to be less.

4)when a gymnast performs gymnastics cushions are kept to increase the time taken to fall and decrease the force applied.

5)when a person is shot through a bullet, he gets severely injured because the bullet moves at a very high speed causing to decrease the time of getting shot and thus increasing force.
