The notion of vertical shot appears in the field of the physical . It is a varied uniform rectilinear movement, also known as MRUV . In a vertical shot, the speed changes and there is an acceleration that is given by the action of gravity.
The vertical shot, whose address it can be descending or ascending, it has a initial velocity which is different from zero. The body in question is thrown up, driven with a certain speed. Then he returns to the starting point with the same speed, although in a sense contrary to what he had at the time of launch.
It can be said, in this way, that the body launched in a vertical shot goes up and then down, returning to the starting point. When the body reached the maximum height , the speed results null . At that moment, the body stops rising and begins its descent. The time it takes for the body to reach maximum height is identical to the time it takes to return to its starting point.
It is important to note that there are several equations that allow to measure different magnitudes linked to the vertical shot. These equations work with variables such as initial velocity , the height and the acceleration .
An example of vertical shooting occurs when we take a tennis ball with one hand and we throw it straight up. This ball will rise for a brief fraction of weather , it will reach its maximum height and then descend, returning to our hand. In practice, however, the vertical shot can be difficult to perform since the throwing may not be straight, the wind can influence the ball, etc.
On the other hand there is the concept of freefall which, while not exactly the opposite of vertical shooting, presents a seemingly complementary situation: it describes the movement of an object that someone releases and drops towards the center of gravity. A fundamental difference between the two is that in the free fall the initial speed is zero , that is to say that a force is not exerted at the beginning but that gravity is responsible for generating the acceleration of the object.
In both concepts, the vertical shot and the free fall, neither the mass nor the weight are used to calculate the time it will take for the object to collide with the surface , nor in the maximum height that it will reach, but the relevant variables are the distance and the initial speed. It is also of great importance the shape of the object that is dropped or thrown, since this can affect its friction with the medium (in this case, the air) and, therefore, in the development of its acceleration.
Since the free fall begins with a zero speed, its movement is considered accelerated , that is, it depends on the acceleration to exist: if there is no gravity, then the object will never move. Needless to say, such a situation cannot take place on Earth, under natural conditions, in the same way that factors such as wind and tilt usually influence vertical shooting, as mentioned above.
With respect to vertical shooting, the fact that the object has a nonzero initial velocity (positive or negative, depending on the direction of the system of coordinates used as a reference) and an acceleration with a sign opposite to it, makes it a movement delayed .
Although the concepts of physics and mathematics often seem too abstract to us and we consider them reserved for those with a specific vocation for numbers, vertical shooting is present in our daily lives in a multitude of situations, although always with factors aforementioned.
