Why Does a Ramp Require Less Force? | Inclined Plane Explained

How does an inclined plane make moving a heavy load easier? This video explains the physics of an inclined plane and shows how ramp length, vertical rise, effort force, resistance force, and friction affect mechanical advantage and efficiency. You'll learn how to calculate: • Ideal Mechanical Advantage (IMA) • Actual Mechanical Advantage (AMA) • Percent Efficiency (%Eff) • Effort Distance (DE) and Resistance Distance (DR) • Effort Force (FE) and Resistance Force (FR) The video also compares a load sliding directly on a ramp with a load moved on wheels, showing why reducing friction can dramatically improve efficiency. For teachers and students: This video can be used as a supplemental learning resource for engineering, physics, and STEM courses covering simple machines and mechanical advantage, including Project Lead The Way (PLTW) courses such as Principles of Engineering (POE) and Gateway to Technology (GTT).
