1. SCIENCE 8 1-1 CIA REVIEW

2. We are learning to: explain motion We are looking for: an act, process, or instance of changing position through time.

3. Which of the following describes motion? A.A change in mass over time B.A change in position over mass C.A change in distance over time D.A change in mass over distance

4. How do you know that the car is in motion? A. The distance between the building and car changes. B. The time it takes the car to move is constant. C. The distance between the building and the car stays constant.

5. What is the SI or metric unit for distance? a)Miles b)Grams c)Meter d)Feet

6. What is used for comparison to tell if an object is in motion? a)direction b)reference point c)Speed d)velocity

7. Do this: From what you know about motion- write a paragraph explaining this video clip

8. We are learning to: explain the difference between speed and velocity We are looking for: Speed = change in distance/ change in time. Velocity = speed + direction of an object. Velocity has a direction, while speed does not.

9. What is the formula needed to calculate speed of an object? A.distance x time B.distance / time C.time / distance D.acceleration x time E.I need help!

10. Joe Shmoe walks 30 meters in 10 seconds. What was his speed? A.5 meters/second B.3 seconds/meter C.3 meters/second D.I need help!

11. What is the only difference between speed and velocity? A.Speed is more complex while velocity is less complex. B.Velocity is time divided by distance and speed is distance divided by time. C.Velocity requires a direction while speed does not. D.Speed and velocity are calculated differently. E.I need help!

12. Which of the following is an acceptable unit for velocity? A.Meters per second B.Feet per hour C.Miles per hour South D.Miles per hour E.I need help!

13. Please copy circle and do this. Speed Fill in three words that closely relate to the one word given. Write a paragraph explaining the significance of each word and how they fit together to form a concept?

14. We are learning to: explain the difference between speed and velocity and interpret graphs. We are looking for: Speed = change in distance/ change in time. Velocity = speed + direction of an object. Velocity has a direction, while speed does not.

15. You are asked to create a graph that shows the speed of an object. What should be plotted on the x and y axes? A.Y axis = speed; X axis = time B.Y axis = time; X axis = distance C.Y axis = distance; X axis = time D.Y axis = time; X axis = acceleration

16. What is this graph showing? A.A person walking at varying speeds. B.A person walking at a constant speed and then stopping to rest. C.A person standing still. D.A person walked three miles.

17. What does this graph show? A.The object is not moving. B.The object is moving at a constant speed. C.The object is moving at a constant speed then stopped to rest. D.The object is moving at varying speeds. Distance 0 Time D

18. What does a steep slope of a line on a distance time graph indicate? A.Speed is fast B.Speed is slow C.The object is not moving D.Speed is changing

19. Graphing Activity Construct a graph in your notes using the data to the right. Be sure to label the x and y axis with correct units. DISTANCE (M)TIME (S) 00 11 32 53 54 55 66 77 88
