Uniform Circular Motion

An object in uniform circular motion goes around a circle at a constant speed. Its velocity keeps turning: it always points along the circle, at a right angle to the radius.

Same speed everywhere, but the velocity keeps turning: it always points along the circle.

In one period $T$ the object travels the circumference $2\pi r$:

$$v = \frac{2\pi r}{T}$$

A point farther from the centre moves faster.
