Types of motion according to the moving intensity (rhythm)
In this category there are two main sub-categories included. They are:
I. Uniform motion. It takes place when an object moves at the same velocity over time. This means it does not change its moving rhythm. Mathematically, we say an object is in uniform motion when in equal time intervals it travels the same distance. Look at the figure below: 
II. Non-uniform motion. This sub-category is further divided into Accelerating (Speeding up) and Decelerating (Slowing down) motion. Accelerating motion occurs when an object increases its velocity over time and Decelerating motion occurs when it decreases the velocity over time.
On the other hand, if the acceleration (or deceleration) is uniform, the object accelerates (decelerates) at the same rate. This kind of motion belongs to the uniformly accelerated (decelerated) motion. If the acceleration (deceleration) is not uniform, this is considered as a non-uniformly accelerated (decelerated) motion.
Look at the figures below for more insight in this concept.
This figure represents a uniformly accelerated motion as the velocity increases by the same rate (in the next second the object travels 2m more distance than in the previous second). If the bicycle doesn't change its moving rhythm, we can find what distance will it travel after a certain time. That's why it is a uniformly accelerated motion.
In this figure, we have a uniformly decelerated motion as the bicycle slows down at the same rate (2 m/s for each second).
In the next figure, you see that the speeding up process is not regular. You are not able to find the velocity after a given time from the data shown. Thus, although it is obvious this motion is accelerated, it is not uniformly accelerated one, as its velocity does not increase by the same rate.
On the other hand, the figure below shows a non-uniformly decelerated motion as the slowing down process does not occur at a regular rate. You cannot foresee what velocity the object will have after a certain period, based on the data provided.
If the motion is irregular, we can split in into small regular sections and making a separate study for each of them.
The scheme below shows how various types of motion based on the moving rhythm are related to each other.
