簡介

Three simple machines are shown sequentially: a lever with fulcrum, a pulley system, and an inclined plane. Each demonstrates the force-distance trade-off — applying a smaller force over a greater distance accomplishes the same work.

Simple Machines

Description

Three simple machines are shown sequentially: a lever with fulcrum, a pulley system, and an inclined plane. Each demonstrates the force-distance trade-off — applying a smaller force over a greater distance accomplishes the same work.

Phases

# Phase Name Duration Description
1 Lever 4s Plank on fulcrum; small force lifts heavy load
2 Pulley 4s Rope over wheel; mechanical advantage shown
3 Inclined Plane 4s Block pushed up ramp vs lifted straight up
4 Principle 2s "Force × Distance = Work (constant)"
