Natiijada casharka
I can describe the movement of objects represented by a distance-time graph.
Muuji qoraalka
A level line on a distance-time graph shows a stationary object (no movement).
The greater the gradient (steeper the line) on a distance-time graph, the faster the movement.
Upward and downward sloping lines on a distance-time graph show movement in opposite directions.
The average speed between two points is calculated using speed = change in distance ÷ time taken.
