Starter: Complete the table and fill in the missing values Stick it in your books
Learning Objectives Draw a distance-time graph. Explain the features of a distance-time graph. Calculate speed from a distance-time graph Learning Objectives Draw a distance-time graph. Explain the features of a distance-time graph. Calculate speed from a distance-time graph Key words speed, distance-time graph, gradient Key words speed, distance-time graph, gradient Distance-time graphs
Task: Copy the results table shown and complete it as the movie is played. Record the distance of the car at five second intervals. Then graph your results. Plotting the distance-time graph Time/SecondsDistance/m Challenge task: Plot a distance- time graph from your results
Time/SecondsSpeed/m/s Task: Plot a distance-time graph from your results Remember: PENCIL and RULER! Plotting the distance-time graph Help! Time on the x-axis, distance on the y-axis Challenge: Calculate the gradient of your graph
What does the gradient of your graph represent? Hint: Gradient = change in y/change in x Speed = distance / time The gradient of a distance- time graph represents the speed.
