Basic mechanics, made visual

Levers, pulleys, beams and friction explained with clear diagrams, so the forces on everyday objects make sense.

How Lever Mechanical Advantage Works

Trading distance for force around a pivot.

How a Pulley Block System Works

Ropes and wheels sharing a load to lift more with less effort.

Momentum Transfer and Collision

How mass and velocity trade during a collision.

Stress Distribution in a Bent Beam

A cross-section view of tension on one side, compression on the other.

Static Friction vs Kinetic Friction

Why it takes more force to start a slide than to keep it going.

Inclined Plane Force Decomposition

Splitting gravity into along-slope and into-slope parts.

Centrifugal and Centripetal Force Model

The inward force that keeps something moving in a circle.

Simple Harmonic Motion Mass-Spring Sequence

A mass on a spring oscillating through its cycle.
