Have you ever seen a drone hovering steadily in the sky and wondered — How does it stay up there?

It may look like magic, but it’s really science and engineering at work!
Every time a drone takes off, four invisible forces start acting on it — Lift, Weight, Thrust, and Drag.

The propellers spin fast, pushing air downwards, and the air pushes back — that’s Lift!
Motors create Thrust to move forward, while Drag resists the motion.
And of course, Gravity (Weight) constantly pulls it down.

In this lesson, you’ll explore the science of flight, understand how propellers and forces work together, and perform your first flight-related activity using simple materials.
