Examples of motion in one, two and three dimensions

To find the examples of motion in one, two and three dimensions, let us first understand the motion in one, two and three dimensions:

1. Motion in one dimension:

The motion of a body is said to be in one dimension or one –dimensional motion if it moves along a straight line in any direction. This type of motion is also called rectilinear or linear motion. Only one position co-ordinate is required to describe the position of the particle in this motion.

Examples (i) Motion of a vehicle on a straight line.

(ii) Motion of a train on a straight railway track.

(iii) Motion of an object dropped from a certain height from the ground.

(iv) A man working on a straight path etc.

2. Motion in two dimensions

The motion of a body is said to be in two dimensions or two dimensional motion if it moves ordinates are required to describe the motion of the particle.

Examples: (i) Motion of an insect on a floor

(ii) Motion of a boat in a river

(iii) Motion of earth around the sun

(iv) Motion of a shell fired from a gun

(v) Motion of a billiard ball on the billiard tale etc.

3. Motion in three dimensions: The motion of a body is said to be in three dimensions or three dimensional motion if it moves in space. In this type of motion three position co-ordinates are required to describe the position of the particle.

Examples: (i) Motion of a kite

(ii) Motion of an aeroplane

(iii) Motion of a flying bird

    Thanks. i didn’t find my answer any where even from Wikipedia. I was trying to find the motion of any object in three dimensions and I’ve found it here. Thank you so much.
