If the direction of movement changes, this is referred to as a movement with non-uniform or variable speed. e.g. B. a fan that spins at a constant speed has a variable speed.

Even speed:Movement of heavy vehicles such as trucks on highways. Uneven speed: Movement of bicycles in town or on busy roads.
When a body travels equal distances at equal time intervals (however small the time interval) in a given direction, the body is moving at a uniform speed. Example: A car moving at a constant speed on a straight road has a uniform speed.
Examples of uniform motion are a car moving at a constant speed, a boy walking along a straight path at a constant speed, etc. The type of motion in which the object moving at different speeds is called non-uniform motion. This means that the object does not travel equal distances in equal time intervals.
The rotation of a ceiling fan’s blades is not an example of uneven motion.
Asteroid motion, a stopped car, and a bouncing ball all travel unequal distances in a time interval, so they are all examples of uneven motion.
If an object travels the same distance in equal time intervals, it is said to be moving at a uniform speed, while an object travels unequal distances in equal time intervals, then it is said to be traveling at a non-uniform speed.
Definition of non-uniform
: non-uniform: such as a : characterized by distinct or changing appearances (in terms of surface, color or pattern) Hence what we see is not a smooth lenticular galactic disk, but an ill-defined and uneven luminous celestial track – the galaxy called the Milky Way.—< /p>
A body has non-uniform motion when its velocity changes over time. Such a body is necessarily under the influence of an external force. An example of uneven motion is a body rotating at a constant speed. Its speed is not constant as its direction of movement changes every moment.
The fundamental difference between uniform speed and variable speed is that a body moving at constant speed has no acceleration, while a body moving at variable speed has some acceleration. Uniform velocity is the vector quantity, while non-uniform or variable velocity is a scalar quantity.
If the speed of an object moving along a straight line is constantly changing, its motion is said to be uneven.
Unevenly Accelerated Motion: When a feather falls in a severe storm, the feather’s speed sometimes decreases and sometimes increases unevenly at equal intervals. It can therefore be referred to as an example of a non-uniformly accelerated movement.
Answer: When a body travels equal distances in a straight line, equal time intervals are called uniform motion. Example: a car moving in a straight line at 20 km/h. If a body travels unequal paths in a straight line at equal intervals of time, it is said to be uneven. Example: spinning wheel.
The car driving in a circular path, varying the angular acceleration each time, is an example of non-uniform circular motion. The car’s speed changes as it accelerates.
Accelerated movements are non-uniform movements. A freely falling body is accelerated as it moves downwards and thus changes its speed during its movement. Therefore, the motion of a freely falling body is not an example of uniform motion.
Question. The movement of a car on a crowded street (option c) is an example of uneven acceleration.
