Therefore since , and is our definition of linear speed, v. Then (Equation 1) Hopefully, it is clear that this formula can only give positive answers, and therefore only can find the . magnitude of the acceleration. Acceleration is a VECTOR so… in . what direction is the acceleration? Centripetal vs. Centrifugal

Angular Speed vs. Linear Speed. Angular speed is the rate at which something turns. The rpm, or rotation per minute, is commonly used for angular speed. Angular speed = # of rotations / time. Or. Angular speed = # of revolutions / time. Linear speed is the distance traveled per unit of time. Linear speed = 2πR(# of rotations) / time. or

This method is appropriate for high speed applications. Figure 2: Velocity Estimation. Once the number of pulses in a fixed time interval is measured the angular velocity of the Quadrature Encoder can be calculated using the following formula: Where, “Encoder Pulses” is the number of quadrature encoder pulses received in the Fixed Time ...
