Science 10 Physics Test Name: Answers Rate of change = change in state v = Δd a = Δv Change in time Δt Δt Part A: Multiple Choice and True False (9). Please circle your answer. 1. How far an object has traveled without any specified direction is indicated by its a) position b) coordinates c) displacement distance 5 1 2. A210.0 dog is walking east at a speed of 5.9 m/s. How long will it take the dog to go oa. 0.028 s m east from the starting point? ob. 35.6 s c. 0.2810 s 5.97 3. The slope of a position – time graph represents 19.8 7.3 12 Siu a. acceleration O b. distance c. velocity 4. Which of the following is a vector quantity? do a. time b. speed go c. velocity it 5. If The final distance of a trip is = +19.8 m, and change in distance is = +7.3m, is what is where did this person start their trip? O a. +2.71 m b. +12.5 m c. + 144.54 m 6. A ball is dropped from rest from the top of a tower. What is the ball’s velocity after 2.2 s? Remember the acceleration of gravity is 9.8m/s2. U a 8 8100 a. 22 m/s b. 19 m d og 7. Which of the following can be determined from a position – time graph? 9.87 21.56 a. distance b. displacement c. all of the above 8. The initial velocity of an object is positive. The acceleration of the object is negative. The velocity of the object tends to oa. decrease b. increase É c. stay the same 9. The rate of change of velocity of an object (i.e. speeding up or slowing down) is indicated by its ___ a) position b) acceleration c) Time 10) Definitions: What is the differences below (4). (A). What is the difference between speed and velocity? (4) Speed is distme time is always and has no direction ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ velocityinvolves the displacement is actual and can be ____________________________________________________________________ negative ____________________________________________________________________ ____________________ True or False? If true, circle T. If false, circle F (8). 11. T F In velocity – time graphs, positive slopes always mean the object is moving if crosses x axis then objet is not moving 0 12. T F Distance is always a positive number because it is a scalar O 13. T F If an athlete runs once around a circular track, her average velocity will be zero. 14. T F O A car that is traveling at 55km/h is moving faster than another car traveling at –55km/h. O 15. T F A horizontal line on a position – time graph means the object is stopped. O 16. T F accelerating. Zero slope on a velocity – time graph means the object is not 17. T F We use distance to find speed and displacement to find velocity. 18. T F O To fine Distance when given time and velocity you divide the two. Circle the best term to go with each of the following definitions (9): 19. Location of an object with respect to a starting point a. displacement O c. position 20. Velocity at the end of a time interval. a. initial velocity (v1) c. final velocity (v2) O 21. velocity at the beginning of a time interval. O a. initial velocity (v1) c. final velocity (v2) 22. a quantity that has magnitude and direction. Oa. vector b. scalar 23. displacement divided by a given time interval. a. average velocity Ob. scalar acceleration 24. equals velocity Oa. slope of a displacement-time graph b. area under a velocity-time graph 25. velocity at one instant in time. a. scalar acceleration b. change in velocity Oc. instantaneous velocity Part B: Diagrams (15) 2.
