Distance/time graphs

-
Gradient (slope) at any point, gives speed of an object
-
Speed of a graph
If the graph is a straight line, the speed at any point is equal to gradient
-
-
If a graph is curved, to find the speed at a certain time, you need to draw a tangent to the curve at a point
Velocity/time graphs
Steeper the graph, the greater acceleration/deceleration

Distance travelled
For bits of graph where accelerations constant you can split area into rectangles and triangles to work it out
You can find area under the graph by counting the squares under like and multiplying number by value of 1 square
