**Tangential Velocity;**

** **

**V=2πr/time **where r is the radius of the motion path and T is the period of the motion

**AngularVelocity;**

**ω****=2π/T=2πf **where T is the period of the motion and f is the frequency

**Angular Acceleration (Centripetal Acceleration);
**

**or **

where** ****ω **is the angular velovity, **r** is the radius and **v** is the tangential velocity

**Centripetal Force;**

**Fc=-m4π²r/T² or Fc=mv****²/r**

** **Where, T is the the period, V is the tangential velocity and m is the mass of the object

** **

**Torque;**

**Τ****=Applied Force.Distance.sinΘ**

**Τ****=F.d.****sinΘ**
