Question

explain the third law of motion with three example

Answer 1

1) A swimmer pushes the water backwards by his/her hands and in return the water pushes the swimmer forwards, thus enabling him to go forward during swimming.

2) A man walking on ground: While walking, a person pushes the ground in the backward direction, and the ground in return pushes the person in the forward direction, thus making him/her to walk.

3) A bird while flying pushes the air downwards with the help of its wings. Consistent with Newton’s third law of motion, air pushes the bird upwards.

4) When a person is lying on a bed, his weight is opposed by a reaction force from the bed (assuming it must be there because of Newton’s third law of Motion). In turn, both forces cancel each other out, and the person enjoys the equilibrium position.

There are a million more examples of Newton’s third law of motion in our environment. If you observe closely, you can find it anywhere and everywhere.

Answer 2

third law of newton is - to every action there is equal and opposite reaction
examples-
1) when we walk , we push the ground backwards , reaction force of ground pushes us forward
2)reaction force of water pushes the swimmer forward in the water
3) A gun recoils due to reaction force of bullet fired by it .
