What is an inclined plane that moves called?

An inclined plane that moves is referred to as a "screw." A screw consists of a helical inclined plane wrapped around a cylindrical shaft. This design allows it to convert rotational motion into linear motion, facilitating tasks such as fastening and lifting. The helical shape creates an angle that functions similar to an inclined plane, allowing for the application of force over a distance, making it easier to move heavy objects vertically.

The other choices represent different simple machines. A wedge is typically a device used to separate objects or portions of material, often resembling a triangular shape. An inclined plane is a static surface that raises objects to a higher elevation but does not inherently involve motion of its own. A pulley is a system of wheels that helps lift loads through a rope or cable but does not constitute an inclined plane. Understanding these distinctions is essential when identifying various types of simple machines in physics.
