Newton's third law is...
"For every action there is an equal and opposite reaction."
This is probably the hardest law to really understand.
It really helps to understand this law if you understand that the law has its origin in the conservation of momentum principle.
The fact of the matter is, force can be most fundamentally understood to be the rate of change of momentum.
Let me explain why.
First momentum is..
P=mv
Now look at the equation for force.
F=ma
It is very similar except that in place of P we have F and in place of v we have a.
Looking at the force equation again..
f=ma
we note that acceleration is the rate of change of velocity so...
F=m dv/dt
Now since the mass, m, is constant we can put it directly beside the velocity like so..
F=d(mv)/dt
This is looking more like the below momentum equation...
P=mv
The only difference is that for the momentum equation, we have, mv, and for the force equation we have the rate of change of, mv, or, d(mv)/dt
Now in the force equation
F=d(mv)/dt
because P = mv, we can replace, mv with P...
F=dP/dt
As I said, force is the rate of change of momentum.
Now since the law of conservation of momentum states that momentum is neither created nor destroyed, if an object picks up momentum, another object to lose momentum. In Newton's third law the "action" force is the second body picking upmomentum and the "reaction" force is the first body losing that momentum.
As an example, imagine two people standing on a very slippery skating rink, because they are standing still, together, they have zero momentum. If one person pushes the second person, or "applies a force" on the second person, the second person has momentum delivered to them and that second person picks up speed/momentum in that direction. The first person however picks up speed/momentum in the other direction, which means that he also had momentum delivered to him. That second person picking up momentum was the "action force", and that first person picking up momentum in the other direction was the "reaction force".
The second person picked up momentum in one direction, and since there is the conservation of momentum law, the first picked up momentum in the opposite direction. Their momentum was zero before the event and since momentum has direction the sum of both momenta add up to zero after the event.
If both people had been moving, for example, to the right and the first person pushed the second person also to the right, the second person would have picked up momentum to the right and the first person would have only lost momentum to the right. There would have still been both an action and a reaction force however because momentum was only exchanged.
Every action has an equal and opposite reaction.
It states that force is equal to the mass multiplied by acceleration produced in the body on which the force acts.
For every action, there is an equal and opposite reaction.
Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."

Equally.
Newton's third law states that if an object "A" exerts a force on object "B", then object "B" will exert the same force (but in the opposite direction), on object "A". This applies to gravitation, as well as other forces.
Newtons third law.
Newtons third law states that for evey action there is an equal but opposite unbalenced force.
That's Newton's third law of motion. A link can be found below.
opposite reaction.
newtons 2nd law states that if a force is put on an object then the object will move in the oppisite direction of the force no thats the third law
It states newtons law of gravitation
newtons third law of motion
Always. Evey object in the universe is experiencing Newtons third law. Just by sitting in your chair motionless you are experiencing Newtons third law.
Newton's Third Law applies everywhere.
Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."
Action and reaction forces are based on Newton's third law of motion. Newton's third law formal states that for every action, there is an equal and opposite reaction.
when a car hits a concrete barricade Newton's third law states the the barricade is hitting back on the car
