In class reading of 4.1 - 4.4

1. Define the following Key Terms: relative, average speed, instantaneous speed, speed, velocity, acceleration.
2. Explain the idea that motion is relative and give an example.
3. Define speed with an equation.
4. Create a 3 part Venn Diagram that compares and contrasts average speed, instantaneous speed, and speed.
5. If you ride a bike a distance of 5 m in 1 s, what is your speed? What is you speed for 10 m in 2 s? For 100 m in 20 s?
6. Answer the questions for section 4.2 (pg 62)and show your work.
7. Explain the main difference between speed and velocity as used in physics.
8. If an airplane travels 500 km due north in 1 h, what is its velocity? If it travels 250 km due north in 1/2 h? 125 km north in 1/4 h?
9. Describe how it's possible to change velocity without changing speed.
10. Define acceleration with an equation.
11. Explain why acceleration is not simply an increase in speed. What other changes can cause acceleration?
12. Describe a situation in which acceleration changes because of a decrease in speed.
13. Describe a situation in which acceleration changes but speed does not.
14. What is the acceleration of a car that goes from rest to 100 km/h in 10s? What is the acceleration of a mechanical part that moves from 0 to 10 m/s in a time of 1s?
15. Answer the questions for section 4.4 (pg 62) and show your work.
