On a velocity/time graph:
- horizontal lines: constant velocity
- sloping lines: accelerating (steeper the line, greater the acceleration)
- line below horizontal axis: negative velocity (object moves opposite direction)
- area under a velocity/time graph: distance travelled (distance= velocity x time/ base x height)
- if the object is accelerating (sloping line), split the shape into a triange (area = 0.5 x b x h) and rectangle and find their areas separately.
