Name: _____________________ Date: ________ Period: ____ Section 3.1 and 3.2 1. Reading guide, pg. 57-66 In a motion diagram, what is happening if each new dot is closer together? . . . . .. (Understanding) 2. How can you find instantaneous acceleration? (hint: A “tangent” line is a line use to see the slope of the line at a particular instant.) (Remembering) __________________________________________________ _____________________________________________ _____________________________________________ 3. If the acceleration vector(arrow) and velocity vector point in opposite directions, does the object speed up or slow down? (Remembering) v a 4. On pg. 60 and 61, what does the book use as a time interval between dots? ____________ (They always use the same time interval for all motion diagrams) (Remembering) 5. Reading pg. 62, what happened in graph D? (Remembering) _______________________________________ _______________________________________ _______________________________________ _______________________________________ _______________________________________ 6. Two pages later, give two ways in which acceleration and velocity are similar. (Remembering) 7. On the next page, what is the shortcut they give you about finding the distance you cover on a v-t graph? In other words, how do you find displacement on a v-t graph? (Remembering) ________________________________________________ ________________________________________________ ________________________________________________ ________________________________________________ 8. By citing evidence from the text, including quotes and a page number, explain what happens to an object’s position time graph when it is constantly accelerating. Use Complete Sentences. (20 points) (Analysis) 9. By citing evidence from the text, including quotes and a page number, make a case for whether acceleration is a vector or scalar. Use evidence from Chapter 2 and Chapter 3. UCS. (20 pts.) (Analysis) 10. Write an example of a sportscaster using physics terms in their sports cast. You must use the following terms appropriately: displacement, velocity, acceleration, and time interval. To get full points for each term, you must explain what the player did that involves that term. “He had good acceleration.” Is not sufficient for points. “Going from the 20 to the 50 yard line in one play is significant displacement!” is sufficient, because it shows understanding of the term.
