When one body exerts a force on the other body, the first body experiences a force which is equal in magnitude in the opposite direction of the force which is exerted
Force is a push or pull acting on an object resulting in its interaction with another object
Types of force
Contact force
Non-contact force
According to Newton, when two bodies interact, they exert force on each other, and these forces are known as action and reaction pairs
When object A exerts a force on object B
Object B exerts a force of equal magnitude and opposite direction back on object A
Newton's third law of motion is associated with conservation of momentum
Examples of interaction force pairs
Propulsion of fish through water
Flight of the bird
Swimmer pushing against the water
Lift created by helicopters
Rock climbers pulling their vertical rope downwards
For every action, there must be an equal and opposite reaction
Aswini and Deepa have identical masses and travel the same distance when they push off of each other and travel in opposite directions
The mathematical representation of Newton's third law of motion is: F_AB = -F_BA
