Properties of mass and weight

Instructor’s choice:

1. Is a person in a roller coaster at the top of the loop actually ‘weightless’? Explain using centripetal/centrifugal force vs. weight.

2. What is the difference between ‘mass’ and ‘weight’? Explain.

Or you may decide which topics to discuss, as long as they are germane to the topics covered in this module.

You could consider the following as good topics for discussion:

  • Did you explore a topic only covered briefly or lightly in the course materials? What did you discover?
  • What concepts (learning objectives) did you struggle with? What resources helped you overcome this hurdle?
