The Linear Speed from Angular Speed calculator computes the linear speed based on the angular speed (ω) and radius (r) from the rotation point.
INSTRUCTIONS: Choose units and enter the following:
- (r) Radius
- (ω) Angular speed
Linear Speed (S): The calculator returns the speed in meters per second. However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The Speed of the Hour Hand clock is either:
- angular speed (ω) is 2π radians per hour or
- linear speed (v) from angular speed is dependent on the length of the hour hand (r) and angular speed (ω)
