Uniform Motion In A Straight Line

Motion in a Straight Line

A body is said to be in a uniform motion if it travels equal distance in equal intervals of time along a straight line.

A distance(x) Vs time(t) graph for uniform motion is a straight line.

The nature of position-time graph of an object in the following cases are-

(I) When Object Is Stationary

Let an object is at rest at a distance a from the origin.

As this distance will remain unchanged with the passes of time, the position-time graph are as-

When Object Is Stationary
When Object Is Stationary

(II) When Object Is In Variable Motion

In a variable motion, the object will cover unequal distance in equal interval of time.

The below graph shows, when an object is in variable motion.

Non-Uniform Motion

A body is in non-uniform motion, if it travels equal displacement in unequal intervals of time.

During non-uniform motion, the speed of the body or its direction of motion or both change with time.
