| Unit Two: Linear Motion Objectives |
| Math Review (See Notes) 1. Explain the benefits of using the metric system. 2. State the other two names for the metric system. 3. List the seven fundamental SI quantities, their respective units, and their unit symbols. 4. Estimate masses, lengths, and volumes in the metric system. 5. Explain the difference between fundamental and derived units. Give examples of each. 6. List the metric prefixes from tera- to pico- and state what they mean. 7. Convert between numbers in the metric system. 2.1 Motion Is Relative 8. Explain the concept that motion is relative. (Give proof.) 2.2 Speed 9. Define speed and give examples of units for speed. 10. Explain the difference between instantaneous speed and average speed. 2.3 Velocity 11. Explain the difference between speed and velocity. 12. Understand the difference between distance and displacement. 13. Describe how to tell whether a velocity is changing. 2.4 Acceleration 14. Define acceleration and give examples of units for acceleration. 15. Describe how to tell whether an object is accelerating. 2.5 Free Fall: How Fast; 2.6 Free Fall: How Far 16. Describe the motion of an object in free fall from rest. 17. Describe the motion of an object thrown straight up until it hits the ground, when air resistance is negligible. 18. Recognize the meaning of the acceleration due to gravity. Math Review (Class Notes) 19. Use the kinematics equations to solve problems for an object moving with a constant acceleration along a straight line. 20. Determine the sign of acceleration relative to the chosen coordinate system. Math Review (Class Notes); 2.7 Graphs of Motion 21. Interpret graphs of position versus time to determine the velocity of an object. 22. Determine from a graph of velocity versus time, the velocity of an object at a given time and the time at which an object has a specific velocity. 23. Calculate the displacement of an object from the area under a velocity/time curve. |
