How is speed calculated
By the speed triangle
How to calculate speed
Distance/ time
How to calculate distance (not moment)
Speed x time
How to calculate time
Distance/speed
When there is a distance / time graph and a horizontal line what does it mean
No movement
On a distance/time graph when there is a diagonal straight line what does it mean
Constant movemnt
On a distance / time graph if there is a curved diagonal one what does it mean
Acceleration
On a speed / time graph if the line is on the bottom horizontal
there is no movement
On a speed / time graph if there is constant movement what would it look like
A high up horizontal line
If there is acceleration on a speed / time. Graph what would it look like
Diagonal straight line
How to calculate gradient
Rise/run
How to see if someth8nbs going slower on a distance graph
See if gradient is less if it is then it’s going slower
How to calculate rate of change of speed on speed graph
Gradient = rise/run
How to calculate average speed
Total d /total time
On a distance time graph how to calculate speed
Gradient = rise / run
