This is actually from my teacher, he's a genius, and it works pretty much every single time :-)
No matter what situation... Draw a force-body diagram for every mass/object/thing that has a force acting on it.
The sum of the forces in each direction in a SINGLE FORCE-BODY diagram always adds to be zero.
Forces always come in pairs.
Label all forces and write the equation (if applicable) for each force.
The net force of the system, if it is accelerating will be defined by the sum of all the forces on the system, F=ma.
Follow these rules, steps, guidlines, and you will be able to solve any force-related problem!
Hope this helps :-)

Example: W = mg, T
The net force of the system, if it is accelerating will be defined by the sum of all the forces on the system, F=ma.
To know when to add or subtract forces, make sure you understand forces are vectors and choose one direction as positive and the other as negative.
Follow these rules, steps, guidlines, and you will be able to solve any force-related problem!
