Answer the Reading Questions below. Please answer each question.

1. How does displacement differ from position?

2. How does the instantaneous speed of an object relate to the instantaneous ve locity of the same object at the same time?

3. On a plot of displacement vs. time, what does the slope represent? What does the slope reperesent on a plot of velocity vs. time?

4.Give an example of a situation where velocity and acceleration are in differ ent directions and an example of a situation when they are in the same direction.

5. Under what circumstances can you use equations 3-16 and 3-19?

6. How does the mass and size of an object affect its motion when it is dropped near the surface of the Earth (neglecting air resistance)?

7. If an object is thrown straight up near the surface of the earth, is there some point in its flight (before it hits the ground) when its instantaneous velocity is zero? If so, where in the flight?

8. If an object is thrown straight up near the surface of the earth, is there some point in its flight (before it hits the ground) when its instantaneous acceleration is zero? If so, where in the flight?

9. When solving problems with more than one object, or more than one important position and time, how should subscripts be used to clarify or simplify the problem?

10. When using the Context Rich Problem Solving method, what kind of drawing must be included when solving problems involving kinematics?

Final Question: (This question must be answered to receive any credit). What is one thing from the reading that you didn't understand or need clarified?
