SYLL. STATEMENTS DUE THE DAY OF YOUR FINAL EXAM Uniform Circular Motion

Find the Relationship between F C and v Mass What were kept constant in this Experiment?  Radius  Mass

Find the Relationship between v and m stopper Mass What must be kept constant in this Experiment?  Radius  Hanging mass (weight)

Find the Relationship between v and r Mass What must be kept constant in this Experiment?  Mass of stopper  Hanging mass (weight)

Circular Motion Lab Results If the sum of the forces on an object is pointed toward a common center of rotation, perpendicular to its velocity, it will travel in a circle at a constant speed.

Warm-up Question (1/10) What is the average speed of the Moon in its orbit given the information below? Answer:

Example Problem #2 What is the average speed of the Earth in its orbit around the Sun given the information below? Answer:

Extra Practice (not covered in class): For each situation draw a force diagram for the object and identify the force / forces / component of force that contribute to the ∑F c that causes the circular motion.
