Unformatted text preview: Graph Matching Assignment #1 & #2 For each of the following situations, sketch a graph with a labeled X & Y axis. You need to make a graph for each of the conditions described. Include description of how the object is moving over time. 1. Sketch a position v. time and a velocity v. time graph for an object ‘at'rest. {A i} nf "ro i: is) t e 2. Sketch a position v. time and a velocity v. time graph for an object moving in a positive direction (away from the origin) with a constantz'sp‘e'ed. x 4' t t 3. Sketch a position v. time and a velocity v. time graph for an object moving in a negative direction (toward the origin) with a constant speed. x ,f Q i: pps‘itiopovbtimeand, 4. Sket ocity v. time graphs for an object positively accelerating from rest. .00""" 5. Why do we call it a positive direction when an object is moving away frgm the origin? 0 \ 0 ° 9 ' claw/i 3 distance is monasan 6. Sketch graphs of the location of a ball along an x-axis when it is speeding up, moving at a constant velocity, and slowing down. Assume timing starts when the ball’s leading edge is at the origin. 0.0 0.2 . 0.0 0.2 0.4 0.0 0.2 0.4 Time (s) Time (s) Time (s) Speeding Up Constant Velocity Slowing Down“ 7. The graph below shows velocity v. time for a remote control car traveling in front of a motion detector. How would the graph change if it was a graph of speed V. time? Sketch it in the available space. Vx (m/s) 8. A graph of the velocity of a remote controlled car t*aveling along a tabletop looks like this: “‘“Siwhs‘qnodfl Vx (m/s) 8a. Describe the car's motion. 8b. During what time or during what interval of time is the car moving most rapidly? Explain your reasoning. BC. This is an v vs. t graph. If you could look at a graph of acceleration vx. Time, how could you estimate the time or time interval on that graph for which the magnitude of the velocity is constant? ...
