Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

Distance-time graphs If an object moves along a straight line, the distance travelled can be represented by a distance-time graph.

Why do you always make a graph in physics lab? It's not just for fun, there is a reason. Here is an example.
