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.
