Angular Momentum needs to be changed with an Impulse (3/4)

This video discusses gyroscopes and uses the bike wheel as a large gyroscope. We use spinning objects to add stability to things that need to remain stable over long periods of time

 

This is again because gravity applies a torque, but to get enough impulse to rotate the thing, this torque must be applied for some time.

Here are some interesting links about gyroscopes
