Chapters

This text is meant to accompany class discussions. It is not everything there is to know about uniform circular motion. It is meant as a  prep for class. More detailed notes and examples are given in the class notes, presentations, and demonstrations. See the links below.

Objectives
Students will be able to:

• Define the period of motion
• Define the frequency for motion
• Mathematically relate the period and frequency
• Convert from RPM’s (revolutions per second) to Hertz
• Use the definitions of period and frequency to solve word problems
• Discuss the relationship between centrifugal and centripetal forces.
• Identify the directions of the vectors.
• Describe why a person slides to the outside of a curve in a car as observed from inside the car.
• Discuss what supplies the centripetal forces
• Correctly write the units equations from memory
• List the S. I. units associates with each quantity
• Solve word problems utilizing the formulas and concepts in the unit.
• Calculate the g’s felt by a rider in an amusement park when
• He/she is spun in a horizontal circle (e.g. carousel)
• He/she is spun in a vertical circle (e.g. roller coaster loops, playground swings.)
• Describe why an irregular shaped roller coaster loop is better than a circular loop.
• Solve problems based on an automobiles ability to supply a lateral acceleration and “cornering.”
• Solve problems utilizing formulas and ratio.

 Mastery Assignment
Teachers, I created and use these animations in class in PowerPoint slide. They drag them in like a picture. They play like movies. Some I reference and use via a web browser.
