Scientific Law = a mathematical way of explaining reality.
Newton's 3rd Law states that forces come in equal and opposite pairs.
We can summarize the law as F = -F.
Or, since F = MA, then MA = - MA.
The ball and head push on each other with equal forces.
"When object A exerts a force on object B, object B will exert an equal and opposite force back on object A."
"When object A exerts a force on object B, object B will exert an equal and opposite force back on object A."
Any time you touch an object, it is touching you with the same amount of force. If you hit a baseball with a bat, the forces are equal and opposite. The ball flies away because it has very little mass and is easy to accelerate. See Newton's Second Law.
The forces here are equal and opposite. Neither the dog nor its owner pulls with greater force. They pull with the same force in opposite directions.
Forces always come in equal and opposite pairs.
This means that the forces are equal even when a big object crashes into a small object.
The forces will be equal when the truck crashes into the car.
Since the car is smaller, the car will have a greater acceleration.
