Question

If it takes a bike wheel 3 seconds to complete one revolution, what is the wheel's angular velocity?

Answer 1

Answer:

angular velocity (w)= theta/time

here theta will be 360

and time will be 3

so (w)=360/3

=120 radius

hope This you mate ✌️

take Care!

Answer 2

Answer:

When objects rotate about some axis—for example, when the CD (compact disc) in Figure 1 rotates about its center—each point in the object follows a circular arc. Consider a line from the center of the CD to its edge. Each pit used to record sound along this line moves through the same angle in the same amount of time. The rotation angle is the amount of rotation and is analogous to linear distance. We define the rotation angle Δθ to be the ratio of the arc length to the radius of curvature:
