Non-uniform motion describes the movement of an object where its velocity changes over time. This change can be in:
* Magnitude: The object's speed increases or decreases.
* Direction: The object changes its direction of movement.
* Both Magnitude and Direction: The object both speeds up/slows down and changes direction.
Key characteristics of non-uniform motion:
* Variable velocity: The velocity of the object is not constant.
* Acceleration: The object experiences acceleration, meaning its velocity is changing.
* Unequal distances covered in equal time intervals: The object covers different distances in the same amount of time.
Examples of non-uniform motion:
* A car accelerating from a stop sign.
* A ball thrown vertically upwards.
* A car moving around a bend.
* A satellite orbiting the Earth.
Contrast with Uniform Motion:
Uniform motion is the opposite of non-uniform motion. In uniform motion, the object's velocity remains constant, meaning it moves at the same speed and in the same direction.
Note: The term "non-uniform motion" is often used interchangeably with "accelerated motion". However, technically, accelerated motion refers specifically to changes in velocity due to a net force, while non-uniform motion simply describes any change in velocity, regardless of the cause.
