We explain what the vertical shot is, what type of movement it corresponds to and what its characteristics are.

The vertical shot is studied by classical mechanics.

What is the vertical shot?

In physical, the vertical throw or vertical throw is a type of movement rectilinear uniformly accelerated (m.r.u.a.) or uniformly varied rectilinear motion (m.r.u.v.).

This is the name given to a type of movement that is the result of throwing an object vertically up (or down) from a certain height H. Once launched, the body rises for a certain weather and then descends in free fall, with a acceleration equal to the value of the gravity. In general, when vertical shots are studied, no type of friction force is taken into account with the air.

Like free fall, vertical throw is often of particular interest within classical mechanics. Vertical launch and free fall are governed by the same type of equations, which are:

y = y0 + v0t + ½. at2

v = v0 + a. t

a = cte

(where a = g, gravitational acceleration)

For the study of this type of movement, a reference system (a Cartesian plane) whose origin is at the foot of the vertical of the point of launch of the object, that is, from the place where the object began to move.

Vertical throw height

In both free fall and vertical throw, the acceleration is that of gravity.

During the vertical launch, the object will reach the maximum height point where the speed is zero and the object is momentarily suspended, just before starting the descent in free fall. To calculate this point, the equations take the following expression:

ymax = y0 + v0. t + ½. g. t2 (equation of position)

0 = v0 + g. t (speed equation)

Vertical throw speed

Something particular about vertical launch has to do with the fact that the object thrown upwards from a height H, with a given initial velocity, in its free fall will leave the initial launch point behind and continue its downward journey. At the moment in which the object passes through the launch point, its speed will take the same value as that it had when the object was launched, but the direction will be the opposite.

In this movement, the acceleration is gravitational (9.78049 m / s2 at the Earth's equator).

If the initial velocity is zero (V0 = 0), then it is not a vertical launch, but a free fall: an object that is released at a height H.
