Circular Motion — three ways to learn it.

The complete written lesson — angular displacement & the radian, ω with period & frequency, v = rω, centripetal acceleration a = v²/r with its derivation, centripetal force and who provides it, banking of roads (tan θ = v²/rg), the vertical circle & the whirled bucket, and the centrifuge — with six worked numericals.

As you scroll, a live panel animates every idea: a ball circles with its tangent velocity and inward force arrows, the string gets ✂ cut and it flies off tangentially, a = v²/r responds live to speed & radius, a motorway curve banks before your eyes, and a vertical loop shows its tension top vs bottom.

Spin, time and measure on a safe virtual bench. All of the course's hands-on physics apparatus lives here.
