[edit] Displacement-Time Graph

In a Displacement-Time Graph, the gradient of the graph is equal to the velocity of motion.

Analysing Displacement - Time Graph

	Gradient = 0 Hence, velocity = 0
	Gradient is constant, hence, velocity is Uniform
	Gradient is negative and constant, hence velocity is uniform and in opposite direction
	Gradient is increasing, hence velocity is increasing.
	Gradient is decreasing, hence velocity is decreasing.

[edit] Velocity-Time Graph

The gradient of the velocity-time gradient gives a value of the changing rate in velocity, which is the acceleration of the object.
The area below the velocity-time graph gives a value of the object's displacement.

	Uniform velocity
	Uniform acceleration hence, velocity is Uniform
	Uniform deceleration
	Increasing acceleration
	Increasing Deceleration

Converting a Velocity-Time graph to Acceleration-Time graph

In order to convert a velocity-time graph to acceleration time graph, we need to find the gradient of the velocity time graph and plot it in the acceleration-time graph.
