Uniform Circular Motion Motion with uniform circular speed along a circular path. – Velocity vector at any point is tangent to path. – All Velocity vectors have the same magnitude (same speed) – Velocity vectors have different direction. Accelerated Motion Velocity is always tangent to the circle and perpendicular to the radial direction.

Uniform Circular Motion (Cont.) The velocity vectors are always perpendicular to the position vectors. – The angle between the vel. Vectors is equal to the angle between the position vectors, ∆θ. For very small ∆θ, the velocity vectors are nearly parallel, and the difference, V, is nearly perpendicular.
