Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. The object may change direction, eg from forward to backwards, up or down, left or right.

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...
