Centripital force: mv^2/r It always points towards the center.

Net force: tangential force + centripital force

  1. When does the net force point towards the center?
  2. What does the tangential force do?
  3. When is the centripital force large? When is it small?

The magnitude of the vectors grow as they should, however the centripital force vector is scaled down by a constant factor compared to the tangential one, so the they fit on the screen.
