What type of gradient can a velocity/time graph have?
Either a positive or negative gradient
What is a velocity/time graph used to show?
How an objects velocity changes over time
Gradient = acceleration because…
acceleration = change in velocity / time
What does a flat section represent on a velocity/time graph?
A steady speed
As a velocity/time graph gets steeper, what happens to the acceleration or deceleration?
It gets greater
What do the uphill sections (/) on a velocity/time graph represent?
Acceleration
What do the downhill sections (\) on a velocity/time graph represent?
Deceleration
What does a curve represent on a velocity/time graph?
Changing acceleration
What does the area under the graph (under the line) represent?
The distance travelled in that time interval
How can you find the distance travelled when the acceleration is constant?
Split the area into rectangles and triangles to work it out
