Sample Flashcards

Formula for speed from a distance-time graph?
Speed = gradient = (change in distance) / (change in time) Speed = (y2 - y1) / (x2 - x1) Units: always check axes — e.g. km/h, m/s, miles/minute
How do you use a conversion graph to convert a value?
1. Find your value on the known axis 2. Draw a line straight up (or across) to the graph 3. Draw a line across (or down) to the other axis 4. Read off the converted value Always use a ruler for accuracy.

Sample Questions

On a distance-time graph, what does a horizontal (flat) section represent?

  • A. The object is moving at constant speed
  • B. The object is accelerating
  • C. The object is stationary
  • D. The object is returning to the start
