MathLiveNewton's third law of motion
States that when one object exerts a force on a second object, the second exerts a force of equal magnitude and opposite direction on the first. It is used to analyse interactions between bodies, such as collisions, contact forces, and the forces holding objects on surfaces.
\mathbf{F}_{12}=-\mathbf{F}_{21}What the symbols mean
| force exerted by object 1 on object 2 (N) | |
| force exerted by object 2 on object 1 (N) |
