Rotation FAQs:


Q: Is rotation a circular movement of an object around a center of rotation?

A: Yes, A three-dimensional object always rotates around an imaginary line called a rotation axis.

Q: Are rotations known as yaw, pitch, and roll?

A: Yes, This terminology is also used in computer graphics.

Q: Is rotation used to mean the movement around an axis?

A: Yes.

Q: Is rotation also used in aviation to refer to the upward pitch of an aircraft?

A: Yes, and particularly when starting the climb after takeoff.

Q: Is rotation measured through Doppler shift or by tracking active surface features?

A: Yes.

Q: Is rotation also a rotation?

A: Yes.

Q: Is rotation opposite?

A: Yes, and by gravity or mechanically.

Q: Is rotation given by the angular frequency or frequency , or period?

A: Yes, The time-rate of change of angular frequency is angular acceleration , This change is caused by torque.

Q: Are rotations expensive to do?

A: Yes, and suffer from a form of gimbal lock where the angles cannot be uniquely calculated for certain rotations.

Q: Is rotation simply a progressive radial orientation to a common point?

A: Yes.

Q: Are rotations never expressed in terms of the external frame?

A: Yes, or in terms of the co-moving rotated body frame, but in a mixture.

Q: Is rotation a commonly observed phenomenon?

A: Yes.

Q: Is rotation a rigid body movement which?

A: Yes, and unlike a translation, keeps a point fixed.

Q: Are rotations called precession?

A: Yes, and nutation, and intrinsic rotation.
