Uniform Speed:
* Constant: The object travels at the same speed throughout its journey.
* Example: A car driving on a straight road at 60 mph the entire time.
Non-Uniform Speed:
* Varying: The object's speed increases, decreases, or changes direction.
* Example: A car accelerating from a stoplight, a roller coaster going up and down hills, or a person walking up a staircase.
Key Characteristics of Non-Uniform Speed:
* Acceleration: Non-uniform speed always involves acceleration, which is a change in velocity (speed and/or direction).
* Uneven Distance Covered: Over equal time intervals, the object will cover different distances due to the changing speed.
* Non-linear Motion: The motion of an object with non-uniform speed is typically represented by a non-linear graph (e.g., a curve).
To understand non-uniform speed better, imagine driving a car:
* Uniform Speed: You're on a cruise control highway with a constant speed.
* Non-Uniform Speed: You're driving in a city, starting, stopping, and changing speed at traffic lights.
In physics, non-uniform speed is a common concept used to describe real-world situations where objects don't move at a constant rate.
