Horizontal projectile motion: comparing free fall and drag resistance

Abstract

<jats:p>The motion of a particle that is projected into a resistant medium and subjected to a uniform gravitational field is considered. The drag force that acts upon the particle within the medium is proportional to the particle’s speed, the density of the medium, and the cross-section area of the projectile. We review the problem of a horizontal motion with a drag force that is linear in speed. The problem is formulated in terms of particle speed, mass, height, time, and expelled gas velocity. The equations of motion are solved analytically, and a case study is discussed. As a result, we obtain the deviation of the projectile as a function of time because of the expelled gases with or without drag force.</jats:p>

Relativistic mean proportion

“…Teaching is a much more important branch of physics than one might think. Indeed, it may also happen that concepts of classical physics, well known to specialists, require further study from a didactic point of view due to the young age of the students [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Generally during the last year of high school, students learn that SR is founded on the principle of relativity and on the fact that the speed of light is a fundamental constant of nature and it does not follow the Galilean law of addition.…”

Computational Solution to the Problems of Projectile Motion under Significant Linear Drag Effect

“…the linear motion)[42], and since the projectile used was spherical then the linear factor is the diameter (D) and was set to be 7.5 cm, mass of the baseball 145 software[44] used in this study is an open-source alternative to commercial programs like IDL (Interactive Data Language) from Research System, and MATLAB software from MathWorks. It was used to run all simulations for this study, and different analytic properties were gladly discussed.…”
