BASIC CONCEPTS ON GRAPH! PHYSICS As LEVEL!!

[The Sarcastic Retard]

I want to learn basic concepts of graph. Like when accn is constant, there is uniform velocity, area under graph of vt gives disp, slope of vt gives accn etc etc...
I have exams tommorow. HELP ASAP.

I will tell all I recall
Velocity: is defined as the rate of change of displacement
Acceleration: is defined as the rate of change of velocity
So if you want acceleration to be constant that is it doesn't change, you need to keep the rate of change of velocity constant ie uniform. v/t should stay the same if V increase so should T in a manner that you can have v/t constant. Since accelerating objects are constantly changing their velocity, one can say that the distance traveled/time is not a constant value.
If we have constant velocity that means Displacement/time is constant. the graph for velocity-time graph with be a straight horizontal line whereas the graph for displacement-time graph will be a straight line passing through the origin.
The area under a velocity-time graph is the change in displacement
The gradient of a displacement-time graph is the {instantaneous} velocity.
The gradient of a velocity-time graph is the acceleration.
