- Q1
Which statement is INCORRECT about angular quantities?

An angle in radians is the ratio of the circumference to the radius.

Objects farther from the axis of rotation will move faster.

The angular acceleration is the rate at which the angular velocity changes with time.

Rotational quantities describe the rotation of an object about a given axis.

Which statement is correct about rotational quantities?

An axis does change direction relative to the frame.

An angle in radians is a pure number and without dimensions.

Angular velocity and linear velocity have the same dimensions.

Every part of a rotating rigid body has the different angular velocity.
