Have you ever used a screw? Pulled something up a ramp? Or used a bottle opener? In physics and technology, we call these "simple machines." But what are they, and how do they work? In this video we go through the six simple machines: The lever, the inclined plane, the wedge, the screw, the wheel and the pulley. We learn about the forces behind these simple machines and see clear examples of how these technical solutions help us with all sorts of things.
