Revolving stopper activity - write up

Claim – how where you able to suspend the stopper (2 forces)

Evidence – calculations, data table, observations, percentage error
calculations. Include diagrams
What might be some possible errors in the experiment?

Reasoning – discuss centripetal force, what was acting on the small mass to
keep it orbiting? What is the direction of gravity? What affects the orbital
period of the stopper. What future questions do you have?

Vocabulary: Direction, gravity, period, Explain centripetal force, centripetal
acceleration in terms of equations
