*Answer and study the following questions to prepare for the test from chapter two. Use
your notes, packet, and text to help you. You will be able to ask questions before the test
during the review. This study guide is worth 20 pts. It is due the day of the test.
1. What is displacement? What two things does it represent concerning the motion of
objects?
2. Find the acceleration of a polar bear that goes from 11m/s to 24m/s in 5 s.
3. Define motion. What changes in order for something to move?
4. A sprinter runs with an average speed of 10.32 s. He runs for 9.5 s. How far does
he run?
5. What two things does velocity represent?
6. How would you describe an object that has an acceleration of -8 cm/s2?
7. How can you calculate all of the things represented in this formula? S=D/T
8. Two rabbits start at the same point and run in a straight line for 5km. At the end of
the run their distances are the same but their displacements are different. Explain.
9. What changes when an objects accelerates?
10. A motorcycle travels to and from a grocery store that is located 3.4km to the west.
What is its distance? What is its displacement?
11. What kind of acceleration is a hiker going up a hill experiencing?
12. At the same speed a basketball is harder to stop than a tennis ball because the
basketball has greater ____________________.
13. What is the net force of balanced forces acting upon an object?
14. What will happen to an object receiving balanced forces?
15. Explain how inertia can cause someone to crash into a windshield.
16. What are the two types of acceleration? Describe the movement of objects
experiencing these types.
17. A car travels 1000 m then turns around and comes back to where it started. What is
the car’s distance traveled? What is the displacement of the car? Which is greater?
18. How does one keep up with their instantaneous speed?
19. A truck changing its speed from 23m/s to 12m/s is undergoing
________________acceleration.

25. Inertia can be different depending on an object’s __________________.
26. How are acceleration and velocity related?
27. What acceleration does a horizontal line represent on a velocity/time graph?
28. Write out the formula for acceleration using symbols and then words.
29. Write the SI units for the following: speed, velocity, and acceleration.
