# Lesson Worksheet: Graphing Speed Physics

In this worksheet, we will practice interpreting graphs of distance and time and graphs of speed and time that represent the motion of objects.

**Q1: **

The changes in the speeds of three objects during the same time interval are shown in the graph.

Which object has the greatest initial speed?

- AThey all have the same initial speed.
- BII
- CIII
- DI

Which object has the greatest final speed?

- AThey all have the same final speed.
- BI
- CII
- DIII

Which object has the greatest average speed?

- AIII
- BThey all have the same average speed.
- CII
- DI

Which object was not moving?

- AII
- BIII
- CI
- DAll the objects were moving.

**Q2: **

The graph shown displays the changes in the distance moved by an object that travels at a constant speed for a time of 8 seconds. The distance axis of the graph has a resolution of 4 meters. Only the values of distance that are integer multiples of 4 are recorded in the table shown.

Time in Seconds | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
---|---|---|---|---|---|---|---|---|---|

Distance in Meters | 0 | 20 | 40 |

What distance value should be entered in the table for a time value of 2 seconds?

What distance value should be entered in the table for a time value of 3 seconds?

What distance value should be entered in the table for a time value of 6 seconds?

**Q3: **

The graph shows the changes in the distance walked by a dog in a time interval of 8 seconds.

At what time did the dog change its speed?

Was the dog’s speed higher or lower before the point when its speed changed?

- AHigher
- BLower

What is the difference between the speed of the dog before and after it changed speed?

**Q8: **

The red and blue lines show the change in distance moved with time for two objects that have the same speed as each other. The distance moved by the object represented by the red line has a value of , and the distance moved by the object represented by the blue line has a value of . The time between the start and end of the motion of the object represented by the red line is , and the time between the start and end of the motion of the object represented by the blue line is .

Which of the following is the relationship between and ?

- A
- B
- C

Which of the following is the relationship between and ?

- A
- B
- C

**Q10: **

The red and blue lines show the change in distance moved with time for two objects.

Which color line corresponds to the object that moves the greater distance?

- AThe blue line
- BThe red line
- CBoth objects move the same distance.

Which color line corresponds to the object that moves at the greater average speed?

- AThe blue line
- BThe red line
- CBoth objects move at the same average speed.
