^Examples of Newton’s third law
- A fireman has to hold the pipe strongly to prevent it form going backward as the water flowing out of the pipe pushes it backwards.
- No action can occur in the absence of a reaction. e.g. in a tug-of-war, one team can pull the rope only if the
other team is pulling the other end of the rope. No force can be exerted if the other end is free. One team exerts the force of action and the other team provides the force of reaction.
- The birds push down on the air with their wings, the air pushes their wings up and gives them lift against the weight.
