Statement I: A concept of pseudo force is valid both for inertial as well as non-inertial frame of reference. Statement II: A frame accelerated with respect to an inertial frame is a non-inertial frame.

A frame of reference that is accelerated with respect to an inertial frame of reference is called a non-inertial frame of reference. A coordinate system fixed on a circular disc rotating about a fixed axis with a constant angular velocity omega is an example of non=inertial frame of reference. The relationship between the force vecF_(rot) experienced by a particle of mass m moving on the rotating disc and the force vecF_(in) experienced by the particle in an inertial frame of reference is vecF_(rot)=vecF_(i n)+2m(vecv_(rot)xxvec omega)+m(vec omegaxx vec r)xxvec omega . where vecv_(rot) is the velocity of the particle in the rotating frame of reference and vecr is the position vector of the particle with respect to the centre of the disc. Now consider a smooth slot along a diameter fo a disc of radius R rotating counter-clockwise with a constant angular speed omega about its vertical axis through its center. We assign a coordinate system with the origin at the center of the disc, the x-axis along the slot, the y-axis perpendicular to the slot and the z-axis along the rotation axis (vecomega=omegahatk) . A small block of mass m is gently placed in the slot at vecr(R//2)hati at t=0 and is constrained to move only along the slot. The distance r of the block at time is

An observer A is at rest in gournd frame, observer B is moving with constant another observer C is moving with constant velocity of 1m/s.

Statement I: A particle is found to be a rest when seen from a frame S_(1) and moving with a constant velocity when seen from another frame S_(2) . We can say both the frames are inertial. Statement II: All frames moving uniformly with respect to an inertial frame are themselves inertial.

A frame of reference F_(2) moves with velocity vecv with respect to another frame F_(1) . When an object is observed from both frames, its velocity is found to be vec(v_(1)) in F_(1) and vec(v_(2)) is equal to
