What is the 3rd of Newton's laws?

Hi Reginald,

Newton’s third law states that for every action there is an equal and opposite reaction. Here, action refers to a force. So if an object A exerts a force on object B then object B also exerts an equal but opposite force on object A.

A real life example is when someone throws a ball, they exert a force on the ball and therefore the ball also exerts a force on the person which is equal in size but opposite in direction. So the person also moves back a little . This can be seen clearly if the person is standing on an almost frictionless surface so they can’t stop their movement, for example on ice

for every action (force) in nature there is an equal and opposite reaction

If an object A exerts a force on another object B, Object B will exert the same force on object A but in the opposite direction to the direction of force exerted by object A

Every action has an equal and opposite reaction.

When two objects interact with one another, they apply a force to each other that is of equal magnitude but opposite direction

Every action has an equal and opposite reaction.

For example if I push a box with a force of 30 Newtons to the left but it doesn't move, then the box must be pushing back the the same (equal) 30 Newtons of force to the right (opposite).

Newton's third law states that every action has an equal and opposite reaction which implies that when two objects interact, they exert and equal and opposite reaction on each other.

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

Text book definition would be "If object A exerts a force on object B, then object B exerts a force of equal magnitude but in the opposite direction on object A." I find students develop misconceptions. I tend to start with is that the idea all forces come in pairs. We call them Newton pairs. Newton pairs are the same size, opposite in direction, of the same type and act on different bodies.

The 3rd law of Newton states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

The third law is known as the law of action and reaction. It states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.

Newton's Third Law of Motion states:

"For every action, there is an equal and opposite reaction."

This law means that if object A exerts a force on object B, then object B simultaneously exerts a force of equal magnitude in the opposite direction back on object A. The forces always occur in pairs, and they act on different objects. This law is fundamental to understanding the interactions between objects and plays a crucial role in explaining how objects move and interact in the universe.

For every force in nature there is an equal and opposite reaction

Hi Reginald,

Newton's 3rd Law of Motion states that for every force there is an equal and opposite and force in nature.

This means that if there are to objects, object A and object B, and object A exerts a force of 60N on the right onto object B, then object B must exert an equal force of 60N in the opposite direction.
