Question

Look at the following pictures and identify the type of motion shown by each of them.

Accepted Answer

The first picture is of a car moving on a straight road. It is exhibiting linear motion or rectilinear motion. Rectilinear motion is a type of translatory motion. Some more examples are the use of elevators in public places and the hot water that falls from a coffee vending machine into the coffee cup.

The second picture is of a bird flying in the sky. It is exhibiting non-periodic motion. It is a random type of motion that does not repeat itself at regular intervals. A body showing non-periodic motion does not return to its initial position after a certain time. Examples are the swaying of the branches of a tree, the movement of particles in the air, etc.

The third picture is of a table fan exhibiting rotational motion. This is because the fan is rotating about its axis without changing the radius of its motion. It is also an example of periodic motion. In a periodic motion, the body repeats its present position after a fixed time interval.

Look at the following pictures and identify the type of motion shown by each of them.
