A particle stays at rest as seen in a frame. We can concude that :

A particle is found to be at rest when seen from a frame S_(1) and moving with a constant velocity when seen from another frame S_(2) . Select the possible options :

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) : A particle is found to be at rest when seen from a frame S,and moving with a constant velocity when seen from another frame S_2 . We can say both the frames are inertial ( R) : All frames moving uniformly with respect to an inertial frame are themselves inertial

A particle is found to be at rest when seen from a frame S_(1) and moving with a constant velocity when seen from another frame S_(2) (a) Both the frames are inertial (b) Both the frames are non inertial (c ) S_(1) is inertial and S_(2) is non inertial (d) S_(1) is non inertial and S_(2) is inertial

Consider the following two statements: A The linear momentum of a particle is independent of the frame of reference. B. The kinetic energy of a particle is independent of the frame of reference

A person applies a constant force vecF on a particle of mass m and finds tht the particle movs in a circle of radius r with a uniform speed v as seen from an inertial frame of reference.

The acceleration of a particle is zero as measured from an inertial frame of reference. Can we conclude that no force acts on the particle?

A constatnt force of 10 N act on a block as shown in figure intal velocity of the particle is zero. It is observed from three frames of reference S_(1),S_(2) and ground. The frame S_(1) start from rest and move with constnat acceleration 10m//s. The frames S_(1)and S_(2) and particle start moving simultaneously at t=0. The rate at which work is done by constant force on the particle is always non-negative when observed fom
