Circular Motion 7 7A. Circular Motion Defining circular motion Circular motion occurs when an object moves in a two-dimensional circular path An object is said to have spin or be spinning if said object rotates about an axis that passes through the object itself If the object circles an axis that does not pass through the object itself, then we say that it revolves about an axis in orbital motion Establishing Position in Circular Motion Definition of radian: one radian is equal to the central angle of a circle that subtends an arc of the circle?s circumference whose length is equal to the length of the radius of the circle There are exactly 2 pi radians in one complete circle Speed and Velocity in Circular Motion
