For the constant negative acceleration graphs the initial displacement is negative and the initial velocity is positive. The velocity time graphs give all three variables for motion–velocity ...

Constant motion happens by itself so long as friction or other influences do not bother it ... Here is the sort of pattern that is produced. Below the line of spots is a graph of the line segments ...

These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still. Acceleration is shown by a straight rising line. Deceleration is shown by a straight ...
