Angular Velocity Centripetal Acceleration Examples of Circular Motion

Circular Motion means that the size of the object traveling in the circle is negligible with the radius of the orbit.

Measuring an angle Definition of an angle Angle = arc length ÷ radius of arc Θ = s ÷ r Unit: radian

Measuring an angle Definition of a radian One radian is the angle measured from the center of the circle when the arc length is the same as the radius of the arc

Measuring an angle Proof that θ = 2π Conversion between radians and degrees.
