Classify the following as motion along a straight line,
circular oroscillatory motion:
(i) Motion of your hands while running.
(ii) Motion of a horse pulling a cart on a straight road.
(iii) Motion of a child in a merry-go-round.
(iv) Motion of a child on a see-saw.
(v) Motion of the hammer of an electric bell.
(vi) Motion of a train on a straight bridge.
(i) Oscillatory motion
While running, the hands move to and fro and
repeat their motion after a given interval of time. Hence, it is
an oscillatory motion.
The horse is pulling a cart on a straight
road. Therefore, it has a motion along a straight line.
Merry-go-round has a circular motion.
Therefore, a child sitting inside it will also have a
(iv) Oscillatory motion
The child on a see-saw goes up and down
continuously. It oscillates up-down. Therefore, it is an
The hammer hits the electric bell and vibrates
rapidly. Therefore, it is an oscillatory motion.
(vi) Straight line
The train is moving on a straight bridge.
Therefore, it has a motion along a straight line.
