Distance and Displacement - Mr. Groth



Distance and Displacement Name

Write definitions for distance and displacement in the blanks below.

1. Distance -

2. Displacement -

*You may leave direction out of your answers for displacement for the rest of the worksheet.

6. For any object in motion, distance is always displacement.

A. less than B. less than or equal to

C. equal to D. greater than or equal to

E. greater than

(over)

7. A bug walks exactly halfway around the edge of a circular cupcake with a diameter of 5 cm.

distance =

displacement =

8. A swimmer swims a half lap, moving from the left end to the right end of a pool that is 50 meters long.

9. A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long.

10. For a typical day in your life, from the time you get out of bed in the morning to the time you climb back into your bed at night, estimate the following:

distance = displacement =

11. Think of the total distance you have covered in your lifetime. Is it

possible for you to move in some direction to reduce this distance to zero?

12. If so, where would you go? If not, why not?

13. Is it possible for you to make your lifetime displacement equal to zero?

14. If so, where would you go? If not, why not?

Distance and Displacement Name

Write definitions for distance and displacement in the blanks below.

1. Distance - (Answers will vary.) The total length of the path taken

2. Displacement - (Answers will vary.) The difference between the final and initial positions, including direction

*You may leave direction out of your answers for displacement for the rest of the worksheet.

| |at home plate |at 1st base |at 2nd base |at 3rd base |back at home |

|distance |0 ft |90 ft |180 ft |270 ft |360 ft |

|displacement |0 ft |90 ft |127.3 ft |90 ft |0 ft |

6. For any object in motion, distance is always D displacement.

A. less than B. less than or equal to

C. equal to D. greater than or equal to

E. greater than

(over)

7. A bug walks exactly halfway around the edge of a circular cupcake with a diameter of 5.00 cm.

distance = 7.85 cm

displacement = 5.00 cm

8. A swimmer swims a half lap, moving from the left end to the right end of a pool that is 50 meters long.

9. A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long.

10. For a typical day in your life, from the time you get out of bed in the morning to the time you climb back into your bed at night, estimate the following:

distance = (Answers will vary.) displacement = 0 m

11. Think of the total distance you have covered in your lifetime. Is it

possible for you to move in some direction to reduce this distance to zero? No

12. If so, where would you go? If not, why not?

(Answers will vary.) No matter what direction you move, distance is always being added to your lifetime total.

13. Is it possible for you to make your lifetime displacement equal to zero? Yes

14. If so, where would you go? If not, why not?

(Answers will vary.) You could return to the place of your birth.

3. The typical baseball diamond is a square 90 ft long on each side. Suppose a player hits a homerun and makes one complete trip from home plate, around the bases, and back to home plate.

Complete the table by finding the player's distance and displacement as he rounds the bases. Include the proper units. All angles are right angles. (Hint: You may need Pythagorean’s theorem for 2nd base.)

4. A runner at a track meet completes exactly one lap around a 400 m track.

distance =

displacement =

5. The runner completes exactly 2 laps around a 400 m track.

distance =

displacement =

distance =

displacement =

4. A runner at a track meet completes exactly one lap around a 400 m track.

distance = 400 m

displacement = 0 m

5. The runner completes exactly 2 laps around a 400 m track.

distance = 800 m

displacement = 0 m

distance = 50 m

displacement = 50 m

distance = 100 m

displacement = 0 m
