After completing the lab, students should derive the full equation for
the centripetal force:
Questions
1. Using words and a mathematical expression, describe the relationship
between force and velocity in uniform circular motion.
2. Using words and a mathematical expression, describe the
relationship between mass and velocity in uniform circular motion.
3. Using words and a mathematical expression, describe the
relationship between radius and velocity in uniform circular
motion.
4. Combine the three relationships above to create one relationship for
force, mass, velocity, and radius. Solve it for force.
