Chapter 8
1. Chapter 8 – Mapping Space and Time 8.1 - Journeys We will find out: that speed is distance over time; v = s / t ; that speed can be calculated from the gradient of a distance–time graph; the meanings of average and instantaneous speeds and how these are calculated from speed–time graphs; the meaning of the area under a speed–time graph and how to estimate this.

3. Speed and Velocity Speed = Distance Travelled / Time Taken = m/s IT IS A SCALAR QUANTITY – IT ONLY HAS MAGNITUDE Velocity = Distance Travelled / Time Taken = m/s IT IS A VECTOR – IT HAS MAGNITUDE AND DIRECTION Distance Speed x Time

6. Distance Time Graph Time (s) Distance (m) Moving at constant speed Stationary Constant speed but faster than A Moving back towards start point What else can we calculate from the graph?
8. Distance Time Graph Time (s) Distance (m) Gradient = Distance /Time = Speed Or dy / dx But it is different at different places?
9. Instantaneous Speed Time (s) Distance (m) What is the speed here? Calculate the gradient of the TANGENT on your graph The Gradient at this point is the INSTANTANEOUS SPEED
10. Average Speed Time (s) Distance (m) What is the AVERAGE Speed for the whole journey? Calculate the gradient of the CHORD on your graph The Gradient of the CHORD is the AVERAGE SPEED
![What is Speed? Velocity? Speed is how far something travels in a certain time… Think about a jet coming into land.. ,[object Object],[object Object],[object Object],Is its speed the same as its velocity???](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
