A particle is found to be at rest when seen from a frame S1 and moving with a constant velocity when seen from another frame S2.

Monjur Alahi

A particle is found to be at rest when seen from a frame S1 and moving with a constant velocity when seen from another frame S2. Mark out the possible options. 

(a) Both the frames are inertial. 

(b) Both the frames are noninertial. 

(c) S1 is inertial and S2 is noninertial. 

(d) S1 is noninertial and S2 is inertial.

(a) Both the frames are inertial.
(b) Both the frames are noninertial.

Explanation:

S1 is moving with constant velocity w.r.t frame S2 . So, if S1 is inertial, then S2 will be inertial and if S1 is non-inertial, then S2 will be non-inertial.

An object of mass, m is moving with a constant velocity, v. How much work should be done on the object in order to bring the object to rest?

The object is in motion, so its energy = kinetic energy = 1 /2 mv2  The kinetic energy of the object, when it comes to rest = 0.  Work done on object...

An object is dropped from rest at a height of 150 m and simultaneously another object is dropped from rest at a height 100 m.

Initial difference in height = (150 – 100) m = 50 m  Distance travelled by first body in 2 s = h1 = 0 + 1/ 2 g (2)2 = 2...

A scooter starting from rest moves with a constant acceleration for a time ∆t1​, then with a constant velocity

(d) > 500N for time Δt1 and Δt3 and 500N for Δt2. Explanation:  During the constant velocity for time Δt2 there is no relative movement between the man and the seat and only force applied by the seat on...

A particle of mass m is observed from an inertial frame of reference and is found to move in a circle of

(d) zero. Explanation: Centrifugal force is a pseudo force needed in an non-inertial frame of reference when we still want to use the Newton's Laws. In this case the frame of reference is inertial, so there is no centrifugal...

A particle is kept fixed on a turntable rotating uniformly. As seen from the ground the particle goes in a circle

(a) 10 cm/s, 10 cm/s 2  Explanation:  Velocity of the particle in a circular motion is equal to ωr , so if ω is constant the velocity is proportional to the radius....

A reference frame attached to the earth (a) is an inertial frame by definition

(b) cannot be an inertial frame because the earth is revolving around the sun (d) cannot be an inertial frame because the earth is rotating about its axis. Explanation: A reference frame attached...

A particle stays at rest as seen in a frame. We can conclude that (a) the frame is inertial

(c) the frame may be inertial but the resultant force on the particle is zero (d) the frame may be noninertial but there is a nonzero resultant force. Explanation:  (a) is incorrect because...

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle.

(c) its kinetic energy is constant (d) it moves in a circular path. Explanation:  Since the force is always perpendicular to the velocity, it means there is no displacement in the direction of...
