• Draw each force acting on an object, including its direction and relative size (as much as possible).
  • Identifying the angle any vectors are from the axis of choice.
  • Being able to choose a good axis for a given problem.
  • Link axis between coupled objects.
  • Identify force pairs between different objects.
  • How to decompose vectors.
  • How to translate the summed forces from the FBD to 2nd law equation.
  • The net sum of the vectors will tell you the vector direction and magnitude of accelration.
