Newton 3rd law
- From Newton 3rd law every action has its own Reaction
- Means Every action have opposite reaction
- For example
- Let gravity g for all acceleration
- Then opposite force applied is = -g
Newton third law
- For eg
- g = -g
Newton third law Limitations
- The internal forces inside a body cancel out from Newton's third law.
- By when we do it on bigger surface's like
- to a wall the force bigger than it can withstand
- The wall wasn't able to withstand the force, it can't provide any force at all, opposite direction to stop the punch
Answer:
statenent: To every action, there is an equal and opposite reaction.
It means that if a body A exerts a force F1 on a body B, and the body B exerts a force F2 on body A.
F1=F2
That is, they are equal in magnitude but opposite in direction.
Whenever two bodies interact, they will exert equal and opposite forces on each other.
This law can be observed anywhere and everywhere in the surroundings. Some of the examples of action-reaction pairs are mentioned below:
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 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 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, the 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.
