Will a Drone Be Pushed Backwards Inside an Accelerating Truck?

Summary by Krater

This video explores relative motion by experimenting with a drone and a neutrally buoyant helium balloon inside a moving truck, concluding that objects with the same density as the surrounding air will move with the air and remain stationary relative to the truck.

From the video

Answers: What happens to a drone or balloon inside a moving truck when the truck accelerates?

• relative motion
• physics experiments
• neutrally buoyant balloons
• drone flight in moving vehicles
• air density and drag

What it concludes

• A drone inside a moving truck moves backward when the truck accelerates because an object at rest stays at rest unless acted upon by an outside force, and the truck's air drags the drone forward.
• A neutrally buoyant balloon with added weight does not move backward when the truck accelerates because its average density matches the air around it, causing it to move with the air.
• A fish inside a bagged container does not move backward when the truck moves because its average density is the same as the water.
• Any acceleration causes a neutrally buoyant balloon to twist rather than move linearly because internal body parts have different densities.
