Picture a spinning gyroscope that has its axis of rotation tilted with respect to gravity. As the gyroscope spins, the direction its axis is pointing is moving. It is describing a circle. That's called precession. Gravity is pulling down (applying a torque) on the gyroscope and trying to pull the top over. Gravity is trying to change the alignment of the axis of rotation. But because the gyro is spinning, because it has what is called angular momentum, gravity can't pull the top straight down. Instead, the force acts 90 degrees later in the direction of rotation. The "down" force is combined with the "spinning" force to create a "sideways" force. The result is that the axis of rotation moves a little bit to the side. In the next instant, gravity, which is still pulling, tries to bring it down, but the spin, that angular momentum, again combines with the gravitational force and another bit of "sideways" force shifts the axis again. In each instant of time, the force of gravity and the gyroscope's spin result in a dynamic that constantly shifts the axis or rotation a bit more to the side. Momentum is conserved in this phenomenon. In an experiment, a top spinning in one direction and tilted as it spins will exhibit precession in a given direction. If the top is spinning in the other direction, precession will be the opposite that it was with the first top. The Wikipedia article on precession has a picture of a gyroscope that has a bit of animation to (hopefully) make it clearer.
What else can I help you with?
Is it true that the seasons are caused in part by the tilt of earths axis?
yes, it is. since the earth's axis is tilted, let's say ur in the northern hemisphere, then when the north side is tilted toward the sun then it's summer. if it's tilted sideways so it's not tilted toward or away from the sun, then it's either spring or fall.
What season occurs in North America when the northern hemisphere is tilted away from the sun?
North America enters fall and then winter seasons as the northern hemisphere is tilted away from the sun. In the fall, the air and earth in North America cools, with falling temperatures and more winds. The leaves on trees change colors, then fall. Winters can be mild to very harsh.
What is the two days of the year on which neither hemisphere is tilted toward or away from the sun?
The Autumnal equinox. It comes on September 22nd.
When the south end of earths axis is tilted toward the sun what season is it?
winter
How does the Earth tilt when it is Spring an Fall?
At the time of each equinox, the rotational axis of the earth is exactly perpendicular to the path of the sunlight hitting the earth. After the autumnal equinox, the hemisphere in which autumn started is tilted away from the sun.
Who invented the first gyroscope?
The first gyroscope was invented by French physicist Léon Foucault in 1852. Foucault's gyroscope was able to demonstrate the Earth's rotation.
What are the parts of a gyroscope?
Rotor gyroscope frame spin axis gimbal
Is it fall spring winter or summer when the earth is tilted away from the sun?
Winter!
What season is it when the Southern Hemisphere is tilted toward the sun in Michigan?
Fall or Winter.
When was Australia - Gyroscope song - created?
Australia - Gyroscope song - was created in 2007.
What is the direction of the precession of the gyroscope?
The direction of precession of a gyroscope is perpendicular to the axis of rotation.
Which simple lab experiment can be used to explain the geophysical concept of precession?
A simple lab experiment to explain the geophysical concept of precession is to use a spinning gyroscope. When a spinning gyroscope is subjected to a force that tries to tilt its axis, it will gradually precess or change its orientation due to the conservation of angular momentum. This mimics the way Earth's axis precesses over time due to gravitational forces from the Sun and Moon.
When the north axis is tilted toward the sun what season is it in south America?
Fall or winter.
Why is there a summer winter and spring and fall?
We have seasons because the Earth is tilted by 23 degrees.
What is the period of precession for this gyroscope?
The period of precession for this gyroscope is the time it takes for the gyroscope to complete one full rotation around its axis due to an external force.
Where is the 3ds gyroscope?
The 3DS gyroscope is planted in the middle of the 3DS, beneath the touch screen.
What was the gyroscope used for?
The gyroscope is used to balance and keep boats and airplane steady By Inori
