Question

Fill in the blanks: Motion of the needle of a sewing machine is ______________.

Answer 1

Hint:The motion of a sewing machine can be understood after looking closely at the movement of the sewing machine. Also classifying the possible motions will help to determine the one that fits in perfectly.

Complete answer:
There are various types of motion however, the three major ones are rotatory motion, periodic motion and linear motion. The rotator motion is the one that moves in a circle and one of the most ancient motions you can say. An example of such a type of motion is the wheels of vehicles and the fan.

The term linear motion is pretty much self-explanatory. It refers to an object that moves in a straight line. The examples of linear motion are in abundance in various graphical topics of mathematics and electric current is one of its practical examples.

Another type of motion is periodic motion. This means the one that moves back and forth, that is, it repeats the same motion after a specific period. The sewing machine is a lot like this motion. In a sewing motion, the needle of the machine moves up and down and follows the same motion after a period of time.

Therefore, the sewing machine follows the periodic motion.

Note: In many places, in place of periodic, it is also said that the sewing motion follows the periodic motion and this is also true as the motion of the needle of the sewing machine oscillates in the same path and has a time period.
