###### Answer: Stays the same

The magnitude of the centripetal force on an object of mass m moving at tangential speed v along a path with radius of curvature r is: = = = → | | where is the centripetal acceleration and is the difference between the velocity vectors. Since the velocity vectors in the above diagram have constant magnitude and since each one is perpendicular to its respective position vector simple vector …

In physics circular motion is a movement of an object along the circumference of a circle or rotation along a circular path . It can be uniform with constant angular rate of rotation and constant speed or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the …

The magnitude of centrifugal force F on an object of mass m at the distance r from the origin of a frame of reference rotating with angular velocity ω is: = The concept of centrifugal force can be applied in rotating devices such as centrifuges centrifugal pumps centrifugal governors and centrifugal clutches and in centrifugal railways planetary orbits and banked curves when they are …

If a body’s speed is a significant fraction of the speed of light it is necessary to use relativistic mechanics to calculate its kinetic energy.In special relativity t…
