Question

Am I correct?


Which statement explains why a bicycle is stable when a rider pedals quickly?
(Points : 1)
The angular momentum vector resists directional change. <-------

Applying a torque does not change the angular velocity of the wheel.

A rotating object acts like a magnet in seeking to point north.

When one object exerts a net torque on another, the second object exerts net torque on the first.



To have the maximum effect in increasing the angular momentum of a potter's wheel, where should you apply a force with your hand?
(Points : 1)
It makes no difference where the force is applied.

You should apply a force with your hand as close to the axis of rotation as possible.

You should apply a force with your hand near the middle of the wheel.

You should apply a force with your hand at the edge of the wheel.<------

Answer 1

I believe these are correct answers. So, i'll stick with them. :)

Answer 2

The angular momentum vector resists directional change. <-------
YES !!!!

You should apply a force with your hand at the edge of the wheel.<------
YES!
