Physics (NTSE/Olympiad)  

1. Motion

Various Graphs Related To Motion

Displacement - Time Graph :
The straight line inclined to time axis in s-t graph represents constant velocity.

In s-t graph the straight line inclined to time axis at angle greater than 90º shows negative velocity

Body with accelerated motion

Body with decelerated motion

Velocity - Time Graph :
For the body having constant velocity or zero acceleration.

The body is moving with constant retardation and its initial velocity is not zero.

The body is accelerated and the initial velocity is zero.

The body is decelerated

Acceleration-time graph :
Acceleration is constant

Acceleration is increasing and is +ve

Acceleration is decreasing and is –ve
