UNIFORM ACCELARETION

when a body travelss an equal amount of distance in equal interval of time it is said to be moving with uniform acceleration

NON - UNIFORM ACCELERATION

when an body travels equal distancw=e in unequal interval of time it is said to be moving with non-uniform acceleration

Acceleration describes the rate of change of both the magnitude and the direction of velocity.

Non-uniform acceleration constitutes the most general description of motion. It refers to variation in the rate of change in velocity. Simply put, it means that acceleration changes during motion. Uniform or constant acceleration occurs in a a type of motion in which the velocity of an object changes by an equal amount in every equal time period. Difference between uniform and non uniform acceleration is that in the first case we have constantly changing velocity and in another case - arbitrary changing velocity, refering both to magnitude and direction of velocity.

Uniform motion :- A body has a uniform motion if it travels equal distance in equal intervals of time, on matter how small this time intervals may be. The distance-time graph for unifrom motion is a straight line.

Non - Uniform motion :- A body has a non-unifrom motion if it travels unequal distance in equal intervals of time, on matter how small this time intervals may be. The distance-time graph for non-unifrom motion is a curved line. Non - Uniform motion is also called accelerated motion.

__Uniform Motion:__

A moving body that travels equal distances in equal time intervals is said to be in a state of uniform motion. The speed of the body is constant.

**Non-Uniform Motion:**

A moving body that travels unequal distances in equal time intervals is said to be in a state of non uniform motion. The speed of the body is not constant.

**Uniform velocity :**

When a body covers equal distance in equal interval of time in a specific direction is said to have uniform velocity.

For example, a car is moving in a straight line with a constant speed of 40km/h.

**Variable velocity:**

When a body covers unequal distance in equal interval of time in a specified direction is said to have non-uniform velocity.

A velocity of a body becomes variable if either its magnitude changes or its direction changes.

For example, a motion of fan is a variable velocity as it changes its direction at every point. So all the circular motions are example of variable velocity.
