How the Wheel and Axle Makes Work Easier

Next Generation Science

This educational video provides a clear and concise introduction to the wheel and axle, one of the six classic simple machines. Using high-quality animations and real-world footage, it defines the mechanism as two connected circular objects of different sizes. The narration explains the physics behind how this machine works, specifically focusing on how the radius of the larger wheel provides a mechanical advantage that multiplies the force applied to the axle or increases the distance the wheel travels.
