Analysing a linear movement

• How much time is there between two "pictures" (time interval)?
• The actual distances in the picture
• Make a table
• Draw a distance-time graph

Why does it matter how many frames per second a camera has, when calculating average velocity?

1. To determine the time between pictures.
2. Because it affects the video quality
3. To determine the distance traveled.
4. To see more details in the pictures.

How is a photo finish camera different from a normal camera?

A motorist can manage an average speed of 70 km/h. He travels a route for six hours. How far has he traveled?

Convert 100 km/h to m/s

1. 0.278 m/s
2. 0.0278 m/s
3. 27.8 m/s
4. 360 m/s
