Q 1-3:

Here are 4 distance-time graphs showing the movement of some atheletes:

Which of these shows.......

1. .....an athelete moving away at constant speed?

2. .....a stationary athelete?

3. .....an athelete moving back to the start at constant speed?

4. The speed or velocity of any object can be measured in

• A. m/s2
• B. N
• C. m/s
• D. m

Q5-7:

Here are some more graphs, showing velocity-time.

Which of these shows.......

5. .....a constant velocity?

6. .....a uniform deceleration?

7. .....a falling tennis ball reaching terminal velocity?

8. Velocity-time graphs can be used to calculate the acceleration and the distance travelled. Which row in the table below shows how is this done?

 To Find The Distance: To Find The Acceleration: A Area under the line Length of line B Length of line Gradient of line C Gradient of line Length of line D Area under the line Gradient of line
