 # Instantaneous Acceleration in Dictionary

The Latin term acceleratĭo came to Castilian as acceleration. The concept refers to the act and the consequence of accelerating: granting speed, increasing speed. For its part, instant is what is generated immediately or lasts for a very short time.

Before moving on to the idea of instantaneous acceleration, it is important to note that for acceleration, an object must change its travel speed. The change of said speed in a temporary unit is what we know as acceleration.

The instantaneous acceleration, as shown on Digopaul, reflects the acceleration that an object at a given time and at a specific point of his career. The instantaneous acceleration can also be said to be the limit of the average acceleration (the division of the speed change by the time that elapses when advancing between two points) at the time the time interval tends to zero (0).

In order to calculate what the average acceleration is, it is essential to have data such as what the speed change is and, of course, the speed every second.

In simpler words, instantaneous acceleration is the acceleration that an object carries at a specific instant. This acceleration can be measured when the average acceleration that is recorded between two very short moments (as close to 0 as possible) is known. When the acceleration between two very close moments is discovered, the instantaneous acceleration is obtained.

In addition to all the above, we can also add that instantaneous acceleration is a vector-type magnitude that is made up of several fundamental and differentiated parts:
-The direction and the direction, which are clearly dependent on the change that the velocity may experience.
-The module, which comes to be represented through Cartesian coordinates. Of course, that representation can be in two dimensions or in three dimensions.

For all this, it can be pointed out that the instantaneous acceleration is equivalent to the speed increase limit that exists when the time period tends to 0.

Because the average acceleration between two points is calculated by dividing the body velocity change by the time it took to pass from one point to the other, instantaneous acceleration is equivalent to the acceleration that is recorded when moving forward for a period close to 0.

No less important is knowing this other set of data about the instantaneous acceleration that concerns us:
-The units of acceleration are fundamentally two. If you opt for the cegesimal system you bet on the use of the Gal, which is a “tribute” to Galileo Galilei. It comes to indicate the centimeter per second. Its equivalence with the international system is that 1 Gal is equivalent to 0.01 m s-2.
-It is not the only kind of acceleration that exists and is studied within the scope of Physics. Thus, we also have tangential acceleration, centripetal acceleration, angular acceleration…
-It is important to know that although the speed of a specific object is positive, its acceleration can be negative. In this way, what would come to show is that the speed is decreasing.
