TYPES OF MOTION GRAPH PHYSICS PROFESSIONAL

This kind of motion typically occurs when we throw an object at an angle Оё different from 0В° and 90В° to the horizontal direction (Оё в‰ 0В° and Оё в‰ 90В°). An elastic spring oscillating up and down when we hang an object in it - as shown in the figure - represents a typical example of Vibratory Motion. This is a back and forth motion around a fixed point, which is known as the 'equilibrium position'. It differs from Circular Motion as here the curve may not be perfect, so it is impossible to find a fixed point whose distance from the moving object remains constant. It describes an object moving according along a curved path. it revolves around a fixed point (the centre) at the same distance (radius r) from it. In this kind of motion, the object moves in a circular path, i.e. The road is straight, so the car is making a rectilinear motion. This is a kind of motion, in which the object moves in a straight line. This category contains a number of subcategories as well. Types of motion according to the path's shape The scheme below shows how various types of motion based on the moving rhythm are related to each other. If the motion is irregular, we can split in into small regular sections and making a separate study for each of them. You cannot foresee what velocity the object will have after a certain period, based on the data provided. 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. 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. You are not able to find the velocity after a given time from the data shown. In the next figure, you see that the speeding up process is not regular. In this figure, we have a uniformly decelerated motion as the bicycle slows down at the same rate (2 m/s for each second). That's why it is a uniformly accelerated motion. If the bicycle doesn't change its moving rhythm, we can find what distance will it travel after a certain time. 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). Look at the figures below for more insight in this concept. If the acceleration (deceleration) is not uniform, this is considered as a non-uniformly accelerated (decelerated) motion. This kind of motion belongs to the uniformly accelerated (decelerated) motion. On the other hand, if the acceleration (or deceleration) is uniform, the object accelerates (decelerates) at the same rate. Accelerating motion occurs when an object increases its velocity over time and Decelerating motion occurs when it decreases the velocity over time. This sub-category is further divided into Accelerating (Speeding up) and Decelerating (Slowing down) motion. Mathematically, we say an object is in uniform motion when in equal time intervals it travels the same distance. This means it does not change its moving rhythm. It takes place when an object moves at the same velocity over time.

In this category there are two main sub-categories included. Types of motion according to the moving intensity (rhythm)

According to the moving intensity (rhythm), andД®ach of the above categories contains in itself a number of sub-categories.

In Physics, the Motion is classified according to 2 main criteria:

We can notice the change in location taking as a fixed point the tree in the photo for example.

In the above figure, different locations of the object during its motion are shown using a professional camera. In few words, anything that keeps changing its LOCATION with respect to TIME is said to be in motion. The frames are merged, so you can see how its location has slightly changed in each interval of time. The following figure shows a cyclist photographed in very short intervals of time. We will discuss all these terms in the next articles of this section (chapter). Mathematically, Motion is described in terms of displacement, distance, velocity, acceleration, speed, and time. In physics, Motion is the phenomenon in which an object changes its location over time. Only then, you realize that the object has moved, because it has changed its location with respect to time. To draw this conclusion, you compare its actual location to any object you consider as fixed (unmoveable) in the surroundings (a building, a tree etc.). However, when you watch it again after having lost your attention for a while, you notice that the object is not anymore at the place where it was before.
