Distance-Time Graphs
A distance-time graph plots distance from a starting point (y-axis) against time (x-axis).
- Gradient = speed: steeper slope means faster speed
- Horizontal line: the object is stationary (distance not changing)
- Slope going down: the object is returning towards the start
- Straight line: constant (uniform) speed
- Curved line: changing speed (acceleration or deceleration)
Formula: Speed = Distance ÷ Time (gradient = rise ÷ run)
Example: A graph shows a straight line from (0, 0) to (3, 120). What is the speed?
Gradient = (120 − 0) ÷ (3 − 0) = 120 ÷ 3 = 40 km/h
