Uniform Motion
* Definition: Uniform motion occurs when an object moves at a constant speed in a straight line.
* Graph Characteristics:
* Straight line: The graph will be a straight line.
* Slope: The slope of the line represents the object's speed. A steeper slope indicates a faster speed.
* Constant Speed: Since the speed is constant, the distance covered in equal time intervals will always be the same.
Example:
Imagine a car traveling at 60 mph on a straight highway. Its distance-time graph would look like this:

Non-Uniform Motion
* Definition: Non-uniform motion happens when an object's speed changes (either increasing or decreasing) or its direction changes, or both.
* Graph Characteristics:
* Curved line: The graph will be a curved line.
* Changing Slope: The slope of the line at any point represents the instantaneous speed of the object. A steeper slope means a faster speed, while a gentler slope means a slower speed.
* Variable Speed: The distance covered in equal time intervals will not be the same.
Examples:
* Accelerating car: As the car accelerates, the distance covered in each second increases, resulting in a curved line that gets steeper.
* Object slowing down: As an object slows down, the distance covered in each second decreases, resulting in a curved line that becomes less steep.
* Object changing direction: If an object changes direction, the distance-time graph will show a change in the slope. It might even have a section that goes down (indicating the object moving back towards its starting point).
Key Points to Remember:
* Distance-time graphs only show the object's motion in one dimension. They don't provide information about the direction of motion.
* The steeper the slope, the faster the object is moving.
* A horizontal line on a distance-time graph indicates the object is at rest.
