SUMMARY

The discussion centers on the physics of free fall and the impact of air resistance on falling objects. It is established that in a vacuum, all objects fall at the same rate regardless of their weight, but this changes when air resistance is considered. The concept of terminal velocity is introduced, indicating that heavier objects may fall faster due to the effects of drag. The user is advised to explore fluid mechanics to better understand the relationship between weight, air resistance, and falling speed.

PREREQUISITES
  • Understanding of basic physics principles, specifically Newton's laws of motion.
  • Familiarity with the concept of drag in fluid dynamics.
  • Knowledge of terminal velocity and its implications in free fall scenarios.
  • Basic programming skills to implement physics formulas in code.
NEXT STEPS
  • Research the principles of fluid mechanics, focusing on drag forces.
  • Learn about terminal velocity and how it affects falling objects.
  • Implement simulations using physics engines such as Unity or Box2D to visualize free fall with air resistance.
  • Explore the mathematical models for calculating drag and terminal velocity.
USEFUL FOR

Physics enthusiasts, programmers developing simulations, and educators looking to explain the effects of air resistance on falling objects.

Okay so first of all forgive me if I sound dumb, and forgive my english, is not my primary language.

So I know two objects will fall at the same rate if air is excluded, so what I am asumming its that free fall formula is only correct if there's no air, right?
So I am a programmer and I want to implement a little of physics, let's say a object weight 1 pound and another weights 10 pounds, I know it will fall at the same speed/rate , if there's no air? but what if i want to consider air, and weight, the heavier object from my logic will fall faster and will touch the ground faster.

So the free fall formula is not what I am looking for? what formula should i consider?
Thanks!

You should consider going through fluid mechanics... the force experienced is directly proportional to velocity...the velocity decreases exponentially until it attains a fixed velocity known as terminal velocity...
