Mechanics (Non Inertial Systems )

Fictitious force =

Coriolis force does work .

• true

• false

A turning car with constant speed is a

• inertial frame of reference

• non inertial frame of reference

The Coriolis force is caused by

• friction

• earth's revolution

• earth's rotation

• temperatures differences

The expression for Coriolis force is given by

• none of these

Coriolis force is zero, when

• angular velocity of rotation is zero

• the particle is rest in the rotating frame

• angular velocity is parallel to velocity of particle

• all of the above

The magnitude of centrifugal force is equal to

Non inertial frames are

• accelerated frames

• unaccelerated frames
