Classify the following as motion along a straight line,circular or oscillatory motion:

(i)   Motion of  your hands while runing.

(ii)  Moton of a horse  pulling  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.

Then now We will see answer of it

(i)It is Oscillatory motion(when we runing the hands move to and fro and repeat motion after a given interval of time.there fore it is an Oscillatory motion

(ii)It is Straight Line(we know that horse is pulling a cart on a straight road.Therefore,it has a motion along a straight line

(iii)It is Circular motion(Merry-go-round is a circular motion. Therefore, a child sitting inside it will also have a circular motion.
(iv)It is Oscillatory motion(The child on a see-saw  goes up and down continuously.it oscillates up-down Therefore, it is an oscillatory motion)
(v)It is Oscillatory motion(The hammer hits the electric bell and Vibrates rapidly Therefore, it is an Oscillatory motion
(vi) Straight line(The train is moving on a string bridge. Therefore, it has a motion  song a straight line)
so Hope that this answer will help you.
