Newton's Third Law

The sound of Newton's Third Law: "If the first thing doing the action (action force) on the second object, then the second thing that will work on the force (reaction force) on the first object of the same magnitude, but opposite direction.
Mathematically it can be formulated :
Action = F - F reaction.

The negative sign indicates that the two forces in opposite directions.
To avoid misunderstanding it is necessary to understand the concept of action as the following reaction:
- Replace the action and reaction on only two objects interact.
- Action and reaction work on two different bodies.
- Action and reaction are the same size but opposite direction.

Examples of everyday events related to Newton's Third Law:
- At the moment we encourage tombok, then the wall will also encourage us.
- At the moment we mennendang ball, the ball rolled forward and we are pushed to the back foot.
- The balloon is inflated and then we release the direction of the wind and the balloon is the opposite.
