Question

From the following cases, which is two dimensional motion ? (a) kite flying on a windy day (b) speeding car on a long straight high way (c) a man is walking on a straight jogging track (d) a planet revolving around its star​

Answer 1

Motion of train on straight track is a one dimensional motion whereas everything else is a two dimensional or three dimensional activity.

Answer 2

Answer:

(a) The motion of kite in the sky is three dimensional motion because the kite while flying may be changing the direction as well as losing or gaining the height, i.e., the motion is in space.

(b) The motion of speeding car on a long straight highway is one dimensional motion, since the motion is confined along a st. line.

(c) The motion of a carrom coin rebounding the side of the board is two dimensional motion, since the motion is confined in the plane of board.

(d) The motion of a planet revolving around its star is two dimensional motion, because the motion is confined in a fixed plane.
