Question

when you ride a bicycle, in what direction is the angular velocity of the wheels? question 15 options: up forwards to your right to your left backwards

Answer 1

Taking ω as a vector quantity the direction is that of a right-hand screw

One can use the right hand and put one's fingers in the direction of rotation (forward if the wheel is moving forwards) and the thumb will point in the direction of the vector quantity ω

In this case ω points to the left giving the angular velocity of the wheel.
