Let’s break down the four main forces that keep drones in the air.
|
Force |
Direction |
What It Does |
Example in Drone Flight |
|
Lift |
Upward |
Helps the drone rise. |
Propellers push air down, air pushes drone up. |
|
Weight (Gravity) |
Downward |
Pulls the drone to the ground. |
Keeps it from floating away. |
|
Thrust |
Forward |
Moves the drone ahead. |
Motors spin propellers faster. |
|
Drag |
Backward |
Slows the drone down. |
Air resistance acts opposite to thrust. |
When Lift = Weight, the drone hovers.
When Lift > Weight, it goes up.
When Thrust > Drag, it moves forward.
