Interpret and sketch distance-time graphs
A lift moves from the ground floor. Distance is measured from the reference point, and time is measured from the start of the journey
Model the motion along one straight route on one side of the reference point. Each moving segment has constant speed with no unshown reversals. S1, S2 and so on label the segments in time order
| Leg | Time (s) | Distance (m) |
|---|---|---|
| S1 | 0 to 2 | 0 to 5 |
| S2 | 2 to 5 | 5 to 5 |
