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 (click here.)

Students should be able to:

  1. Describe Galileo's experiment that lead to his conclusions about inertia
    • Describe how this experiment is exemplified in modern day amusement parks
  2. Define in a sentence Galileo's Law of Inertia (Alias-Newton's first Law of Motion)
  3. Describe what affects an object's inertia.
  4. Characterize rotational inertia
    • Describe the relationship between an objects rate of spin and the object's distribution of its mass.
  5. Define “inertial mass” and compare it to “gravitational mass.”
  6. Give examples of how inertia is demonstrated in everyday life
  7. Write in words Newton's Second Law of Motion.
    • Describe a force
    • Give the SI and English unit of force.
    • Give the symbols for force in SI and English systems.
  8. Describe the relationship between force and acceleration.
  9. Describe the relationship between force and mass.
  10. Do problems that make proportionality predictions based on Newton’s second law of motion. (F=ma) [ Ratio problems ]
  11. Describe the formula for calculating weight from mass. (w=mg)
    • Describe what is means to experience a certain number of g’s.
    • Convert back and forth between g’s and m/s2.
  12. Write in a complete sentence Newton's Third Law of Motion.
  13. Apply Newton’s Third Law of Motion to Problems.
  14. Be able to identify the "reaction force" in a given situation.
  15. Distinguish between the concepts of mass and weight.
  16. Memorize the value for the acceleration of any object near the surface of the Earth.
    • Describe what it means to be weightless.
  17. Utilize Newton's Laws in conjunction with the Kinematics equations to solve problems.
  18. Demonstrate understanding of each law by describing how the law is exemplified in a video clip or animation.
