[[Force and Translational Dynamics]]
|
|
|
|
Each force has an equal and opposite reaction.
|
|
|
|
If I push a wall with 50N's, it'll push back with 50N's, called an action reaction pair.
|
|
In formula format it's $F_{AB}=-F_{BA}$. The negative sign shows the forces point in opposite directions.
|
|
This also means that if 2 objects push off each other their COM doesn't change.

Tension is a force applied by flexible connectors.

An ideal <small>yisang</small> string is one with **negligible mass and does not stretch**. In these ideal strings tension is equal throughout, in non ideals tension differs in different parts. |
