Speed =
- distance × time
- distance ÷ time
- time ÷ distance
- time - distance
The difference between speed and velocity is:
- velocity is speed in a given direction
- speed is velocity in a given direction
- speed is the gradient of the velocity time graph
- velocity is a more scientific word for speed.
The units for acceleration are
- metres second
- metres per second
- metres per second squared
- metres second squared
Acceleration =
- speed ÷ time
- time ÷ speed
- time ÷ change in speed
- change in speed ÷ time
Acceleration is:
- the area under the distance time graph
- the area under the velocity time graph
- the gradient of the distance time graph
- the gradient of the velocity time graph
Speed is:
- the area under the distance time graph
- the area under the velocity time graph
- the gradient of the distance time graph
- the gradient of the velocity time graph
Distance is:
- the area under the distance time graph
- the area under the velocity time graph
- the gradient of the distance time graph
- the gradient of the velocity time graph
A tachograph plots:
- an acceleration-time graph
- a speed time graph
- a velocity time graph
- a distance time graph
The gradient of a graph is
- rise ÷ run
- run ÷ rise
- rise × run
- run + rise
When working out acceleration from a gradient:
- only a small rise and run are needed to ensure accuracy.
- large rise and run are needed to ensure accuracy, but the units are not important.
- large rise and run are needed to ensure accuracy, and the correct units are important.
- the area and units are important
