The angular velocity of a wheel is 70 rad/sec

WebThe wheel circular velocity (rps, revolutions/s) - n rps - can be calculated as. n rps = (6.94 m/s) / (2 π (0.665 m) / 2) = 3.32 revolutions/s. The angular velocity of the wheel can be calculated as. ω = (3.32 revolutions/s) (2 π rad/revolution) = 20.9 rad/s. The kinetic energy of the rotating bicycle wheel can then be calculated to WebThe greater the rotation angle in a given amount of time, the greater the angular velocity. The units for angular velocity are radians per second (rad/s). Angular velocity ω ω size 12{ω} {} is analogous to linear velocity v v size 12{v} {}. To get the precise relationship between angular and linear velocity, we again consider a pit on the ...
