Motion Test - 3

According to the question the correct option will be ‘A’ because a book lying on the table is at rest.

Since no net external force is acting on the book in this state and so it is not capable of moving the book.

According to the question the correct option will be ‘A’ because When tuning is on a table, a large sound is heard. It creates the forced vibration of a table. As a result of a sound also comes out from the table which has much larger intensity.

According to the question the correct option will be ‘A’ because All oscillatory is periodic, as in all oscillatory motion particle repeats its position after a certain interval of time.

According to the question the correct option will be ‘B’ because the motion of the hand is an oscillatory motion, as the motion repeats in a finite interval of time and the to and fro motion happens in a given time period

As the hand moves to one extreme, a restoring force acts in the opposite direction to move it back to the mean and then to the other extreme position. Thus, the bye-bye gesture of the hand is an oscillating motion

According to the question the correct option will be ‘B’ because a body is said to be at rest if it remains in one position for a long time.

All the three object are in any oscillatory motion w r t to earth as frame of reference. But study table is at rest.

So study table is odd one out of the four objects.

According to the question the correct option will be ‘B’ because the equation for displacement in oscillation is x = A sin (ωt+α)

Since x is a sine function of time, the graph is sinusoidal in nature.

According to the question the correct option will be ‘C’ because Flapping of wings was oscillatory, since it constitutes to and fro motion, while birds motion along a circle is periodic

According to the question the correct option will be ‘A’ because for a motion to be SHM, it has to be small amplitude and the acceleration is proportional to the displacement of the particle and directed against its displacement. Here the acceleration has centripetal and tangential components (here zero since uniform circular motion) but has no variation with particle displacement hence can be oscillatory but not in SHM.
