When I rotate my head with 1rad/s , I can see a body which 350000km away have velocity greater than c.is that possible?
I didn't got this, i think a problem with siteNugatory said:Check out the first few posts in this thread: https://www.physicsforums.com/threa...-our-Earth's-rotating-reference-frame.936332/
Just rotate head in night sky, you will see stars are rotating, v=r ×omegakuruman said:By what logic will the body appear to have velocity greater than c? What you see is the light emitted by the body about 1.2 s earlier.
Have you tried turning your head at 1rad/s? Was it possible?Sandeep T S said:When I rotate my head with 1rad/s , I can see a body which 350000km away have velocity greater than c.is that possible?
Please try again. That (long) thread should answer your questions about this thought experiment.Sandeep T S said:I didn't got this, i think a problem with site
Yes, a body can have angular velocity without having linear velocity. Angular velocity refers to the rate of change of an object's rotational position, while linear velocity refers to the rate of change of an object's position in a straight line. So, it is possible for a body to rotate without moving in a straight line.
Yes, angular velocity and rotational velocity are essentially the same thing. They both refer to the rate of change of an object's rotational position.
No, according to Einstein's theory of relativity, the speed of light is the maximum speed at which any object can move in the universe. Therefore, a body cannot move faster than the speed of light, whether it is in a straight line or rotating.
Yes, angular velocity and linear velocity are related to each other. The linear velocity of a point on a rotating object is equal to the product of its angular velocity and the distance from the axis of rotation. This is known as the tangential velocity.
Yes, angular velocity can be negative. A negative angular velocity indicates that the object is rotating in the opposite direction of the chosen axis of rotation. This is commonly seen in objects such as wheels or gears that can rotate in either direction.
