Sci. Doc Distance-time graphs Learning Objectives Describe what the gradient of a distance-time graph gives. Explain the different types of distance-time graphs. Keywords Distance Time Speed Velocity Gradient Calculate speeds from distance-time graphs. Do Now I do We do You do Test

Sci. Doc Distance-time graphs A distance-time graph can be used to see when an object is stationary or travelling at a constant speed. The steeper the slope, the faster the speed. The gradient (slope) of a distance-time graph shows the speed. LO: I do We do Stretch: How can we calculate the gradient of a straight line? You do Test

Sci. Doc Speed from a distance-time graph You can calculate the speed from the gradient of a distance-time graph. This is because of the equation for speed: Stretch: What is the speed between A and B Distance (km) D 50 40 30 B 20 10 v=s÷t 1 LO: C I do We do 2 3 You do 4 5 6 Time (h) Test
