Mechanical Systems
- 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 necessarily the same force.
