The Hovercrafth. PBL project.
A hovercraft is a vehicle that glides over a smooth surface by hovering upon an air cushion. Because of this, a hovercraft is also called an Air-Cushion Vehicle, or ACV
The hovercraft creates vents or currents of slow-moving, low-pressure air that are pushed downward against the surface below the hovercraft.
Surrounding the base of the ACV is a flexible skirt, also called the curtain, which traps the air currents, keeping them underneath the hovercraft. These trapped air currents can create an air cushion on any smooth surface.

Newtons 3rd law of motion- A force is a push or a pull upon an object that results from its interaction with another object. Forces result from interactions!
