If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve.

When displaying a journey, the vertical axis will often represent the distance from a particular place rather than the distance travelled. Such graphs are known as displacement-time graphs.

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

Kinematical Graphs The ‘displacement-time’ and the ‘velocity-time’ graphs of a particle are often used to provide us with avisual representation of the motion of a particle.
