Solids and fluids behave in some similar ways, and in some fundamentally different ways. Here are some of the highlights.

Solid & Fluid Materials

The mechanics behind a basic structural element of animals and plants.

Cantilevers

Bodies don't just move, they spin, and there's a special kind of momentum and inertia that applies there.

Torque and Angular Momentum

Inertia comes in several flavors. Here they are.

Moments of Inertia

Newton's Laws of Motion

Momentum and force are fundamentally linked through Newton's Laws of Motion.
