Draw a picture with all the forces acting upon it. (F.B.D)
Assign a direction to be positive. (F.O.R) + usually preferred for the direction of acceleration.
Write a relationship for the sum of the forces
in the x and y direction.
Substitute and solve for unknown terms
this may need to be done repeatedly
In a system that includes Multiple Bodies:
write the equation for each body
write an equation for the combined system
* Note: If objects are bound, they must share the same motion but not necessarly the same force.
