Question
Explain why you do not tip over when riding a bicycle but do tip when stationary at a stoplight. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. precess are not rotating gyroscopes are rotating When you ride a bicycle, the rotating wheels have momentum that tends to keep the wheels spinning at a constant rotational speed about the axis of rotation. The wheels behave like If the bicycle starts to tip over, the pavement will exert a torque on the front wheel that causes the spinning wheel to so that it turns in the direction that the bicycle is tipping. near On the other hand, if the wheels ,then there would be no gyroscopic effect to stabilize the bicycle pendulums accelerate angularExplanation / Answer
a) when you ride a bicycle, the rotating wheels have ANGULAR momentum that tends to keepthe wheels spinning at a constant rotational speed about the axis of rotation.The wheels behave line GYROSCOPES.
If the bicylce starts to tip over, the oavement will exert a torque on the front wheel that causes the spinning wheel to PRECESS so that it turns in the direction that the bicycle is tipping.
On th eother hand, if the wheels ARE NOT ROTATING, then there would be no gyroscopic effect to stabilize the bicycle.
B)When you place your fingers on the top of a spinning raw egg, the spinning will stop, but resumes when you remove your fingers. The reason is because wheile the egg SHELL stops spinning, theLIQUID inside the raw egg will keep spinning.
On the other handm a hard bioled egg can be regarded as SOLID. So when you place your fingers on top of the egg, the spinning motion STOPS ENTIRELY.
