If an object moves in a circular path with uniform ________, its motion is called uniform circular motion
speed
In uniform circular motion the object moves along a circle covering equal arc-lengths in equal times — i.e. at constant speed.
Velocity is not uniform because its direction (tangent to the circle) changes continuously; this changing velocity implies a centripetal acceleration \(a_c=\dfrac{v^2}{r}\) whose direction also keeps changing. Only the scalar speed stays constant.
