Question

Choose the correct statement for motion in three dimension:

• A. Train moving on a circular track
• B. A flying eagle
• C. Motion of a boat in a river
• D. None of the above

Answer 1

The correct option is B A flying eagle

One dimensional motion is a motion along a straight line in any direction.

In a two dimensional motion, a body moves along x and y-axes at the same time.

In a three dimensional motion, a body moves along x, y and z-axes at the same time i.e. a body moves in space.

As a flying eagle, moves along all three axes at the same time (moving in space) therefore it is a three dimensional motion.

Whereas, train on a circular rack and boat in a river, move in x and y directions therefore these are two dimensional motions.
