Newton’s third law states that for every action there is an equal and opposite reaction. So if you push on a wall, the wall is exerting the same force on you

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. In simpler terms, this means that if you push on something, it pushes back on you with the same amount of force. For example, if you press your hand against a wall, the wall pushes back against your hand with an equal force.

For every actions there is an equal and opposite reaction. You experience this all the time - standing on a hard floor or pushing against a solid wall.

For every action (force exerted on an object) there is another force exerted which:

- is qual in magnitude

- is opposite in direction

- is colinear (same line of action)

- is the same type of force e.g. gravitational, electromagnetic

- acts on the opposite object (Object A exerts force on B, then B exerts force on A)

To every action, there is an equal and opposite reaction. This can be observed when you push yourself against a wall with your hand (apply an action), the wall pushes back on your hand with an equal and opposite force (instant reaction). Although the wall doesn’t move, but the forces are still there. And you feel the force from the wall pushing back on your hand.

Newton's third law states that to every action there is an equal and opposite reaction. For example if we fire a bullet from a gun then we experience a force in opposite direction. to the direction of bullet.

Newton's 3rd Law of Motion state that:

For every action, there is an equal and opposite reaction

This law describes the relationship between two objects interacting with each other. When object A exerts a force on object B, object B simultaneously exerts an equal and opposite force on object A. E.g

1. When you push on a wall, the wall pushes back on you with the same force.


2. When you throw a ball, the ball exerts an equal force back on your hand.


3. When a car accelerates forward, the ground exerts an equal force backward on the car's wheels

1. Equal forces: The forces exerted by both objects are equal in magnitude.


2. Opposite directions: The forces are directed in opposite directions.


3. Simultaneous: The forces occur at the same time.

Applications includes:

1. Rocket propulsion: Expels hot gases backward, propelling the rocket forward.


2. Jet engines: Expels air backward, generating forward thrust.


3. Walking: Your feet push backward on the ground, propelling you forward.

Mathematically

F₁ = -F₂

where F₁ and F₂ are the forces exerted by objects 1 and 2, respectively

If body A applies a force on body B, then body B will apply an equal and opposite force on body A

If body A exerts a force on body B.

Body B will exert an equal and opposite force (of the same type) on Body A

Newton's 3rd Law of Motion is very simple: "For every action, there is an equal and opposite reaction."

This means that whenever one object pushes or pulls on another object, the second object pushes or pulls back with the same amount of force but in the opposite direction. For example, if you push against a wall, the wall pushes back against you with the same force, even though the wall doesn’t move.

It’s like when you jump off a boat: you push down on the boat with your feet (action), and the boat pushes you upwards (reaction). Fascinating question: Ever wondered how you move forward when you walk?

Does this make sense, or is there anything you’d like me to explain further?
