CIRCULAR MOTION CALCULATOR
Circular motion calculator calculates centripetal acceleration, angular velocity, speed, period, frequency and radius parameters of a uniform circular motion in physics.
Formulas used for calculations are given in the "List of Equations"
section.

Centripetal Acceleration (a_{c}) 


Note: Default rounding is 5 decimal places.
Definitions:
Centripetal Acceleration (a_{c}):The rate of change of tangential velocity.
Frequency (f): The number of rotations of object around the circle per second.
Period (T): The time required for one complete revolution of the object around the circle.
Speed (V): Describes how fast an object is moving.
Velocity: Describes both how fast and in which direction the object is moving.
List of Equations:
Frequency 
f=1/T 
Angular velocity 
w=2π/T 
Speed 
v=2πr/T=wr 
Centripetal acceleration 
│a_{c}│=v^{2}/r=w^{2}r
