Discussion Overview

The discussion revolves around finding an equation for projectile motion that incorporates air resistance. Participants explore the complexities of modeling such trajectories, particularly in relation to artillery applications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks a single equation that accounts for air resistance, given initial velocity, range, and change in elevation.
  • Another participant notes that incorporating air resistance complicates the equations, making them non-linear and coupled, thus not easily solvable in a general way.
  • A numerical simulation is suggested as a common method to predict projectile trajectories under the influence of air resistance.
  • Further inquiry is made about how to implement numerical simulations for this purpose.
  • Participants mention the availability of resources, such as books and online pages, that explain various methods for conducting numerical simulations.

Areas of Agreement / Disagreement

Participants generally agree that air resistance complicates the modeling of projectile motion, and that numerical simulations are a viable approach, but there is no consensus on a specific equation or method to achieve the desired outcome.

Contextual Notes

The discussion highlights the limitations of finding a straightforward equation for projectile motion with air resistance, emphasizing the need for numerical methods and the complexity involved in such calculations.

Not in a general way. Air resistance can be complicated, and it makes the nice two (both coordinates) linear, independent equations for a free fall non-linear and coupled.
A numerical simulation of the path is a common way to predict a trajectory.
 
So how could I do it?
 
Numerical simulations? There are tons of books and internet pages explaining various methods.
