Clockwise at same rpm
In the Northern Hemisphere, the Coriolis force deflects winds to the right. This causes hurricanes and typhoons to spin counterclockwise. In the Southern Hemisphere, the Coriolis force deflects winds to the left. This causes hurricanes and typhoons to spin clockwise.
The rotation of the Earth has a negligible effect on a bullet fired from a gun. While the Earth rotates at a speed of around 1670 kilometers per hour (1037 miles per hour) at the equator, bullets travel at much higher speeds. Typically, bullets travel at speeds of several hundred to a few thousand kilometers per hour, making the influence of the Earth's rotation on their trajectory insignificant.
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
When the Earth is traveling, everything on the Earth is traveling with it, in the same frame of reference.
For example, when you are in a car or an airplane and you flip a coin in the air, the coin doesn't shoot backwards. Or, notice that when you jump upwards that the Earth didn't move from under you when you jumped.
Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis,fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist.In more basic terms, torque measures how hard something is rotated
Centripetal force is a force that makes a body follow a curved, as opposed to straight, path; it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path.
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
That refers to the centrifugal force.
Without getting into the difference between linear and angular momentum,
it should be enough to simply point out that the Earth's mass is equal to
the mass of something like 60 thousand billion billions of you, and that for
equal momentum, the velocities would be in the inverse of the same ratio.
In case of Russian dance, the dancer will spin her body about the vertical axis passing through her toe. If she keeps extending her hands then number of rotation and so angular velocity will be less. If she brings her hands close to her body then number of rotations would increase. Same scene could be enjoyed in case of circus with girls hanging just with a tight hold with their teeth.
Yes, if it's constrained to the circular path. YOUR body does that on several amusement-park rides.
Centripetal force = mv2/r, where m is mass, v is the velocity, and r is the radius
-- The angular velocity is
one revolution/minute = 360 degrees/minute = 6 degrees/second .
(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, or
slowing down ... then the angular acceleration of any of its hands is zero.
Angular momentum is defined as the moment of linear momentum about an axis. So if the component of linear momentum is along the radius vector then its moment will be zero. So radial component will not contribute to angular momentum
Anything that's spinning, rotating, tumbling, or traveling in a
closed path around something else, has angular momentum.
