Circular Motion

• Frequency is how often a particle passes through a point (Hz)
• Period is how long it takes for a particle to complete a cycle (s)
• A Radian is the angle where the radius is equal to the arc length (360 = 2pi)
• Angular Velocity is the rate of change of angular displacement (Rads/s)
• Tangential (Linear) Velocity is the velocity of a particle moving in a circle and acts tangent to the circular path
• Centripetal Force is the resultant force acting on a body moving at a constant speed in a circle and acts towards the centre of a circle
• Centripetal Acceleration 


  In order for an object to maintain a circular path, its velocity must constantly be changing direction and accelerate toward the centre of the circular path
