Jumping is the physical action of propelling oneself rapidly upward such that momentum causes the body to become airborne. (wiki en.)
Long jump - means the distance jump is very similar to the row. We throw our body in the jump. Our muscles are the driving force.
The high strength obtained from the muscles gives a high initial speed (boy) or less (girls) which affects the distance of the jump
The student making the jump must give his body speed in two dimensions.
In the horizontal (ox) from this speed, the range of the jump is the distance traveled in the horizontal dimension
vertically (oy) from this velocity the height of the jump results
Movement in the horizontal dimension presents the equation
Movement in the vertical dimension represents the equation
The solution to the equations results in the equation for the range of the projection
The range of the jump depends on the initial speed and the angle of the velocity vector. We obtain the maximum range for the angle of 45 degrees.
Using the equations of motion, we can write the equation of the track
This equation has the form of a polynomial
y = bx – ax2
It is the equation of an inverted parabola
