This unit explores the key concepts of circular motion and universal gravitation, focusing on important terms like period, frequency, tangential velocity, centripetal force, and more. Discover how these concepts relate in various contexts, such as NASCAR laps, rubber stopper rotations, and planetary revolutions. Engage with examples that illustrate the principles, including the relationship between gravity and centripetal force, and gain insights into Isaac Newton's contributions to physics and our understanding of these phenomena.

Checking for understanding Unit 10: Circular Motion and Universal Gravitation Monkemeier Physics
Define and state the relationship between the following terms. • Period • Frequency • Tangential velocity • Circular motion • Rotation • Revolution • Centripetal force • Circumference
Frequency or Period? • The NASCAR completes one lap in 200 seconds. • A rubber stopper whirls on the string 5 revolutions in 20 seconds. • The planet completed one revolution in 230 Earth Days. • We measured the Yoyo as having 6 revolutions in 12 seconds. • A record player had 33.3 rotations per minute. How do you KNOW the difference?
Gravity – Can Act as a Centripetal Force! • What is so GREAT about Issac Newton?
