✦ Displacement - Time Graph :-
The graph will be a straight line.
The gradient of the line shows velocity.
The steeper the gradient the higher the velocity and vice-versa.
Positive gradient shows the body moving away from the starting point (forward).
Negative gradient shows the body coming back to the initial position (backward).
✦ Velocity - Time Graph :-
The vertical axis of a velocity-time graph is the velocity of the object.
The horizontal axis is the time from the start.
When an object is moving with a constant velocity, the line on the graph is horizontal.
When the horizontal line is at zero velocity, the object is at rest.
✦ Acceleration - Time Graph :-
The area under an acceleration graph represents the change in velocity.
In other words, the area under the acceleration graph for a certain time interval is equal to the change in velocity during that time interval.
