@miramar4life did you listen to the lecture? it has nothing to do with air resistance

@miramar4life, the reason behind the difference in time is due to difference in their MOMENT oF INERTIA , as torque = I * alpha

@miramar4life If that were true, then why doesn't a larger solid cylinder of the same mass as a smaller solid cylinder go slower?

Ok, this gay hi wants to drop dust in our eyes with that lection for kids.that gyro effect the military they use for antigravity and lection like that full with stupid explonations just ..... brain wash to be not study in a deep

i believe that the reason for the hollow tube to be slower than the solid tube is because of air resistance....if they were first placed in a vacuum and then let go they would reach the bottom at the same time....anyway, overall great presentation

@zopilote1986 google 'feynman gyroscope diagram' for an alternative explanation

Hmmmm....I don't think spin is compatible with total momentum conservation. What happens if you apply a linear force to accelerate a wheel?The wheel spins and you are pushed back with the wheel....
