Example of Free Fall and Vertical Throw

The Freefall It is the movement of a body that goes from a height in the air, towards the ground, without braking or being affected by an external force or acceleration other than that exerted by the Gravity.

It's about a uniformly accelerated motion that begins at that high point from where the object is dropped, and ends on the first surface it faces to stay at rest.

The Earth exercises that attraction call Gravity, which is the one that supports us with our feet on the floor. This attraction affects everything that is close to the planet, and it is of course the one that causes bodies to fall, and that the moon remains fixed at that distance to describe its trajectory, instead of going away through the Universe.

The attraction of Gravity has the characteristic that is giving an acceleration to the bodies. This increase will be constant in speed, and has a value of 9.81 meters every second squared. This means that every second, the speed will increase by 9.81 meters per second. This acceleration is represented by the letter g.

If an object is dropped from a great height, you will have a better chance of hitting the ground with higher speed. The way to calculate that maximum speed with which the object reaches the final surface is by multiplying the acceleration of gravity g for the time the body lasted in Free Fall. The following equation describes this calculation:

The above calculation has been used even in rural areas to empirically determine the depth of the wells from which the water for domestic use is extracted. The procedure consisted of dropping a stone from the edge of the well, and making the calculation later using the time it took to hear the arrival of the stone to the surface that marked the level of the Water.

Another characteristic of Free Fall is that if it is performed without interruptions as forces or objects that intervene in its trajectory, it will always be Vertical and straight.

Differences between Free Fall and Vertical Pull

The differences between a Free Fall move and a Vertical Pull are straightforward. The main ones are listed:

-The Freefall is straight and vertical, but only towards the ground, down. The Vertical shot It is also in a straight line, but it can be up or down.

-The Freefall allow the body to fall no non-gravity influences. In the Vertical shot, there's a initial effort put into the body, such as a pitch or a climb, before releasing it.

Vertical shot

The Vertical shot is the movement caused to a body in which it is going to move in a straight line, vertically, either up or down. Get two names then: Vertical Up Shot and Vertical Down Shot, respectively. Each one is explained below:

Vertical Up Shot

The Vertical Up Shot is one in which a body is thrown into the sky. When starting this movement, the body has a maximum speed, starting from the hand or the machinery that is launching it.

Later, on its way through the air, the attraction of the gravity will counteract this movement, slowly braking the object, with a negative acceleration of 9.81 m / s². Given this phenomenon, there is going to be a time when the object is completely decelerated.

Upon reaching a vertical speed of 0 m / s, it will remain in an instant suspended in the air, to be affected immediately by the acceleration of gravity, now if in a positive sense, experiencing a Fall Free. One would only have to wait for the object to return to the ground through that Fall.

Given the previous movements, it can be said that the Upward Vertical Pull always involves a part going and a return part of the object, forming then of two movements: Rise and Free Fall.

The Vertical Up Shot is characterized by the fact that an effort is placed on the object to make it rise as high as possible.

Vertical Down Shot

Throwing an object on the floor is the most common case of Vertical Down Shot. It is different from Free Fall because not only is the object dropped, but it is thrown with an applied downward force. In this way, the object is jointly influenced by that force and that of gravity.

 The Vertical Down Shot will have only one path, to the ground, in comparison with the Vertical Up Shot, which describes the double path, back and forth.

Another characteristic that distinguishes the Vertical Down Shot is that thanks to the effort of the At the beginning, the movement will have an initial speed, which will naturally increase with the gravity. Contrary to Free Fall, which begins with the rest of the hand that holds the object to be released.

2. A boy jumping from a high platform to the ground
3. When the rain escapes from the clouds to reach the crops
4. When a liquid is poured into a glass from a high point
5. The feathers that are shed from the body of birds are affected by gravity despite their lightness
6. When the coffee is filtered, the scented water rushes into the final carafe 
7. Newly hatched birds, shortly after hatching, when their plumage is already developed, they throw themselves from the nest to, after a brief free fall, take flight with their at.
8. When an asteroid or space dust particle comes into contact with the Earth's gravitational field, it will be affected by it, to begin a free fall to the surface.
9. Falls are the natural sign of free fall. They are waters that rush to reach a river or another body of water, after crossing one that was higher.
10. When a stone is dropped into a well, gently releasing it.
11. In the melting of the polar ice caps, great masses of ice break off from the heights, to reach the frozen sea in a free fall.

6. When a basketball is bounced, it is first thrown downwards to make it bounce.
7. When a person bungee jumps, which is a long bungee cord tied around the ankles, he first has free fall and when the rope is stretched to the maximum, it returns the person in a slight ascent, thereby restoring its length original.
8. One of the ways to play with young children is by throwing them in the air less than half a meter high over the hands of the adult who is having fun with them. It is pleasant for both of us.
9. When a basketball player scores a touchdown by driving the ball to the basket, and "nails" it, he is striking a vertical shot through the hoop.
10. When the goalkeeper of a soccer team is training, he uses medicine balls, which have an additional weight compared to normal ones. He develops strength, with upward and downward throwing exercises.
