Question

Rotating frames of reference are:

• A. frames that have ficititous forces
• B. Inertial frames
• C. Frames that moves with constant velocity along a straight line
• D. None of these

Answer 1

The correct option is A frames that have ficititous forces

A fictitious force (also called a pseudo force) is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference, such as a rotating reference frame.
All rotating frames are non-inertial forces and a fictitious force acts on the particle
Thus option (a) is correct
