SPEED & VELOCITY.
DISTANCE TIME GRAPHS.
These are all distance-time graphs; they are called this as the distance is plotted against the time.
The slope on the graph represents speed.
The steeper the slope, the greater the speed.
We calculate speed with the following formula:
Speed- Distance/time
However, this formula can be rearranged to work out distance:
Distance- Speed X time.
Or time:
Time- distance/ time.
The best way to remember all these formulas is with the triangle:

How to calculate speed form a distance time graph.
Speed= gradient= vertical/horizontal
EXAMPLE:
Using the graph, work out the speed the car was moving at , at 6 seconds.
Speed= gradient= vertical/horizontal= 6seconds/10metres=
0.…read more
