Answer:
Newton's third law of motion states that every action has equal and opposite reaction.

✓✓Define Newton's third law of motion.
To every action is an equal and opposite reaction.
- Force always acts in pair.
- Action and reaction acts on two different objects.
Others law of motion are :-
➥Newton's first law of motion states as if a body at rest with remain at rest or in uniform motion will continue in uniform motion unless and unbalanced force acts on the body.
➥According to Newton's second law the rate of change of linear momentum of a body with respect to time is directly proportional to the unbalanced force applied on the body and change in momentum take place in the direction of appiled force.
Let's know about momentum:-
➥momentum is defined as quantity of motion contain in a body.In other words it is also defined as product of mass and velocity.
- momentum is represent by p.
- momentum is a vector quantity.
- Direction of momentum is along the direction of velocity.
- SI unit of momentum is kg m/s.
- CGS unit of momentum is g cm/ s.
