Write third law of motion? Give two examples?
Answers
Answer:
Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. ... In reaction, a thrusting force is produced in the opposite direction. Hence an equal and opposite reaction is produced for each action.
Two examples are:
2) A man walking on the 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 walk.
3) A bird while flying pushes the air downwards with the help of its wings. Consistent with Newton’s third law of motion, the air pushes the bird upwards.
