Question
Give any two examples to explain Newton's third law.
✓

Answer

Newton's third law : "Action and reaction forces are equal in magnitude and opposite in direction but theseforces act on different objects." When an object applies force to another object it is called action. The force that second object exerts on the first object is called reaction force.
For example: (i) When a swimmer performs an action by pushing water backwards with his hands, the pushed water pushes the swimmer forward with the same reaction.
(ii) The action by which the person rowing the boat pushes the water back is equal to reaction that the water provides to the boat to move forward. Many other incidences of daily life can also be understood on basis of Newton's third law of motion.

Spring fitted doors close by themselves when released. You want to keep the door open for a long time, say for an hour. If you put a half kg stone in front of the open door, it does not help. The stone slides with the door and the door gets closed. However, if you sandwitch a 20g piece of wood in the small gap between the door and the floor, the door stays open. Explain why a much lighter piece of wood is able to keep the door open while the heavy stone fails.
