What are the Elements of Movement?

The movement elements they allow a clear and precise definition of what movement is and how it works, not only in general but in the world of physics in particular. To begin it is necessary to know the concept of movement, in order to understand the function of its elements.

Movement in physics is the change of position of an object or body, taking into consideration a specific reference point and time. If the object has not changed its position, it is said to be at rest.

Main elements of the movement

Acceleration

Acceleration is considered a vector quantity. Thanks to it you can calculate the variation of speed per unit of time. The unit that represents it in the International System is m/s² (meter per second squared).

The acceleration can be divided into several movements, but the two most used are the uniform circular movement and the accelerated rectilinear movement:

Uniform circular motion: is where the object to be studied travels a circular path following a constant speed.

Accelerated Rectilinear Motion: is when the object travels a straight trajectory and its acceleration remains constant. A clear example of this movement is free fall, where the constant acceleration corresponds to that of gravity.

start and end position

They are the points where the trajectory traveled by a body or object begins and ends.

Speed

Speed ​​can be defined as the relationship between the distance covered by a moving body and the time spent on the journey.

The term Speed can be easily confused with the term Speed. Although it is true that in the vocabulary of science they can be used as synonyms, each one has a somewhat different definition.

The most noticeable difference would be the fact that the Speed has a vector character while the Speed is the module of that magnitude.

Time

It is a magnitude with which the duration of the movement is measured.

Trajectory

It can be defined as the set of points in a straight or curved line that a body or object runs through when making a movement.

vector scroll

The displacement vector is the one that defines the position of the object from point A to point B.

The displacement vector takes into account only the initial position and the final position of the object, its trajectory is not important when calculating said vector.

Speed

Velocity is a vector character that expresses the distance traveled by an object in a given unit of time.

To define it, the direction of the displacement and the module (the speed) are necessary. Its unit in the International System is the symbol m/s (meter per second).

There are several types of speed:

Average speed: is the change of position in a specific time interval.

instant speed: is the tangent to the trajectory.

Average speed: is the average of the final and initial velocity where a constant acceleration is included.
