After learning about Coupled systems we expect you to be able to:
  • Identify when two or more objects are coupled systems, such as one block stuck to another, vs uncoupled systems, when one block is sliding over another.
  • To identify what are the constraints on the coupled system. Is a1= a2 or is a1 = 2*a2?
  • Distinguish force pairs from forces that are simply equal, such as the the tension on two ends of a rope.
  • Be able to use knowledge of coupled systems and constraints with Newton's 2nd_law
  • Be able to use Newton's 3rd law and identify force pairs between two interacting objects..
  • Be able to label force pairs on a FBD
  • Using the fact that the magnitude of two forces that are a force pair are equal to help solve problems involving Newton's 2nd law
  • Be able to identify how the magnitude of the kinematic variables of two connected objects are related to each other.
  • Understand how the relationships between kinematic variables in coupled systems are used to analyse physical situations.
