  1. Unit 5 Jeopardy Speed Velocity Acceleration

  2. Jeopardy Final Jeopardy

  3. What is the speed of a car that has gone 60 meters in 20mins? Step 1 D = 60 meters T = 20 minutes S = ? Step 2 s = d/t Step 3 S = 60m/20min Step 4 3m/min Speed for 100 Back

  4. Step 1 D = 50 meters T = ? S = 10m/2min = 5m/min Step 2 t = s/d Step 3 T = 50m/5m/min Step 4 10 min Speed for 200 • If school is 50 meters away from Janet's’ house, how will it take her to get to school if she walks 10meters in 2min? Back

  5. Person A is traveling faster than person C both have a constant speed Speed for 300 A B C What is the difference in speed between person A & person C? Back

  6. Draw a graph for the following scenario: From home, Nicole begins to drive to the store at constant speed. She stops at the stop sign and remembers that she has to go to the bank that is 40 meters past her house. Once she gets to the bank, she doesn’t have her ATM card and has to return home. (Note: All speeds are constant) Speed for 400 Back

  7. Write a brief story explaining in the graph. Speed is constant - then the speed is constant but faster – stops – turns around fast constant speed – slower constant speed Speed for 500 Back

  8. It takes Sara 90min to get to Tucson from Phoenix (180km). What is her velocity Step 1 D = 180 kilometers T = 90 minutes V = ? Direction - South Step 2 V = d/t + direction Step 3 S = 180m/90min (south) Step 4 2km/min South Velocity for 100 Back

  9. An Amtrak train travels from Phoenix to Flagstaff 240miles in 6 hours. What is the trains average velocity? Velocity for 200 • Step 1 • D = 240 miles • T = 6 hours • V = ? • Direction - North • Step 2 • V = d/t + direction • Step 3 • V = 240mi/6hr North • Step 4 • 40mph North Back

  10. When lines on a velocity-time graph intersect, does this mean that the two cars are passing by each other? If not, what does it mean? No! When lines intersect on a v-t graph, it means that the two cars have the same velocity. When lines intersect on a p-t graph, it means that the two cars are passing each other. Velocity for 300 Back

  11. Draw a velocity/time graph from the following position/time graph Answer Velocity for 400 Position (m) Back

  12. Identify the type of motion for each area in the velocity/time graph 1 = Acceleration 2 = Constant Speed 3 = De-acceleration Velocity for 500 2 3 1 Back

  13. What is the definition of acceleration? (Be specific) A change in velocity Change in direction or change in speed Acceleration 100 Back

  14. Acceleration for 200 • Draw a positive acceleration on a position/time graph Back

  15. A train is traveling at the speed of 50m/s at the top of the hill. 5 seconds later it reaches the bottom of the hill moving 70m/s. What is the rate of acceleration of the train? Step 1 Final V = 70m/s Original V = 50m/s T = 5 sec A = ? Step 2 A = Final V – Orig. V Time Step 3 A = 70m/s – 50m/s 5s Step 4 4m/s/s Acceleration for 300 Back

  16. Acceleration for 400 • A = Blue Car • B = Red Car • C = Green Car • Match the appropriate line to the particular color of car. Back

  17. A ball rolls down an inclined plane with a constant acceleration of 2 m/s2: a) how fast is the ball traveling after 3 seconds? b) how far has the ball traveled in those 3 seconds? c) how far has the ball traveled by the time its velocity is 20 m/s? a) v = a x t V = 2 m/s2 x 3s = 6 m/s b) d = v x t d = 6 m/s x 3 sec = 18m c) t = v/a t = 20m/s / 2 m/s2 T = 10s d = v x t d = 20m/s x 10s d = 200m Acceleration for 500 Back

  18. Identify the following graphs based on their units. Position/Time Velocity/Time Acceleration/Time 1 meters Sec 2 m/s Sec 3 m/s/s Sec Graphs Galore for 100 Back

  19. Draw a velocity time graph for the following scenario: Jim rode his bike down the mountain until it leveled out and he rode at constant speed. Then he started accelerating down the mountain again. Velocity Graphs Galore for 200 Back

  20. Draw 3 position time graphs that represent: An object stopped An object traveling at constant speed An object accelerating 1 2 3 Graphs Galore for 300 Back

  21. Draw a velocity time graph, based off the following graph: Time (s) Time (s) Velocity (m/s) Velocity (m/s) Position (m) -5 -4 -3 -2 -1 0 1 2 3 4 5 Time (s) Graphs Galore for 400 Back

  22. Draw a position/time graph, a velocity/time graph, & an acceleration time graph for the following data: Position/Time Velocity/Time Acceleration/Time Graphs Galore for 500 Back

  23. What is the difference between speed and velocity? Velocity is speed in an given direction Anything is game for 100 Back

  24. What does the slope of a position/time graph represent? What does the slope of a velocity/time graph represent P-T = Velocity V-T = Acceleration Anything is game for 200 Back

  25. What do the following units represent? 25mph 102km 5.5km/hr/sec 6min - 74m/s Speed Distance Acceleration Time Velocity Anything is game for 300 Back

  26. Write a brief story explaining what is happening with person C and person D Person C is traveling in a positive direction and D is traveling in a negative direction need to mention speed change. Anything is game for 400 Back

  27. Describe the motion in detail of Albert, Bob, and Charlie Anything is Game for 500 • Albert is accelerating • Bob is also accelerating, but not a much as Albert • Charlie is running at constant speed, stops for 4 seconds and then accelerates to 100 meters Back

  28. Final Jeopardy • Name the motion for the following graphs: + Acceleration De-Acceleration Constant + Velocity Constant - Velocity Acceleration in the - direction Constant + Velocity & Constant - Velocity Acceleration & De-acceleration Stopped

  29. And the winner is….. You! Good Luck on your test! Study, Study, Study!!!
