A didactical exposition of the classical problem of the trajectory determination of a body, subject to the gravity in a resistant medium, is proposed. Our revisitation aims to show a derivation of the solution to the problem that is as simple as possible from a technical point of view, so that it can be understood by first-year undergraduates. A central role in our analysis is played by the so-called chain rule for derivatives, which is systematically used to remove the temporal variable from… 

Approximate Analytical Description of the Projectile Motion with a Quadratic Drag Force

In this paper, the problem of the motion of a projectile thrown at an angle to the horizon is studied. With zero air drag force, the analytic solution is well known. The trajectory of the projectile

Approximating the linearly impeded projectile by a tilted idealized one

At the introductory level, projectile motion is usually considered under the assumption of the absence of air resistance. Even the simplest case of linear drag might be beyond the students, as it

On projectile motion with quadratic drag force

We present the results of numerical calculations of the influence of air drag force, quadratic in speed, on the values of such characteristics of projectile motion as maximum height, maximum range of

Deterministic physical systems under uncertain initial conditions: the case of maximum entropy applied to projectile motion

The kinematics and dynamics of deterministic physical systems have been a foundation of our understanding of the world since Galileo and Newton. For real systems, however, uncertainty is largely

Determining the velocities and angles for a free kick problem

The free kick problem is considered for three distinct cases: (i) no air drag or lift, (ii) linear drag, and (iii) linear drag and lift. For the first case, closed form formulas are derived for the

Angry Birds realized: water balloon launcher for teaching projectile motion with drag

A simple, collapsible design for a large water balloon slingshot launcher features a fully adjustable initial velocity vector and a balanced launch platform. The design facilitates quantitative



An analytic solution of projectile motion with the quadratic resistance law using the homotopy analysis method

We consider the problem of two-dimensional projectile motion in which the resistance acting on an object moving in air is proportional to the square of the velocity of the object (quadratic

Projectile motion with air resistance quadratic in the speed

We consider two‐dimensional motion of a projectile experiencing a constant gravitational force and a fluid drag force which is quadratic in the projectile’s speed. The equations of motions are

An analytic approach to projectile motion in a linear resisting medium

The time of flight, range and the angle which maximizes the range of a projectile in a linear resisting medium are expressed in analytic form in terms of the recently defined Lambert W function. From

A block slipping on a sphere with friction: Exact and perturbative solutions

A well studied problem in elementary mechanics is the location of the release point of a particle that slides on the surface of a frictionless sphere when it is released from rest at the top. We

Fall with linear drag and Wien's displacement law: approximate solution and Lambert function

We present an approximate solution for the downward time of travel in the case of a mass falling with a linear drag force. We show how a quasi-analytical solution implying the Lambert function can be

On the rise and fall of a ball with linear or quadratic drag

We review the problem of a vertically thrown ball, with a drag force which is either linear or quadratic in the speed. It is stressed from the outset that these two types of drag correspond to

Analytical investigation of point mass motion in midair

The classic problem of the motion of a point mass thrown at an angle to the horizon is reviewed. The air drag force is taken into account with the drag factor assumed to be constant. An analytical

Analytic Approximations of Projectile Motion with Quadratic Air Resistance

We study projectile motion with air resistance quadratic in speed. We consider three regimes of approximation: low-angle trajectory where the horizontal velocity, u, is assumed to be much larger than

The fly ball trajectory: An older approach revisited

An older approach to the problem of projectile motion with quadratic drag force is presented with the fly ball as an example. In this approach, analytical solutions for the velocity, curvature, and
