An object may appear to be moving for one person and stationary for some other. For the passengers in a
moving bus, the roadside trees appear to be moving backwards. A person standing on the road–side perceives
the bus along with the passengers as moving. However, a passenger inside the bus sees his fellow passengers
to be at rest.
Most motions are complex. Some objects may move in a straight line, others may take a circular path. Some
may rotate and a few others may vibrate. There may be situations involving a combination of these.
(a) Can any object be at absolute rest?
(b) Is displacement a scalar quantity?
(c) Define oscillatory motion.
(d) Define mechanics.
