Yes. the needle uses reciprocting motion
A reciprocating object is one that moves back and forth in a straight line, such as a piston in an engine or a sewing machine needle. These objects alternate their motion between two positions in a repeated manner.
The motion of the needle in a sewing machine is vertically, rapidly up and down.
What does the stop motion screw do on the sewing machine
motion of the needle of a sewing machine is what is the motino is this?
No
A Reciprocating motion is a up and down or back and forth motion in objects. as we move a saw in a back and forth movement it is a Reciprocating Motion. I got this ans. after doing research in Reciprocating motion in 7th grade

In very crude terms, rotary motion is round & round, reciprocating motion is back & forth. A piston engine has both kinds of motion. The crankshaft displays rotary motion, the pistons display reciprocating motion. The camshaft displays rotary motion, the valves display reciprocating motion. Out on the suspension, the wheels display rotary motion and the shock absorbers display reciprocating motion. (One might say the shocks don't display "true" reciprocating motion because they're not CONSTANTLY in motion, but that one drives on better roads than they have here!)
A sewing machine works in slow motion by using a needle to push thread through fabric, creating stitches. The machine moves the fabric back and forth while the needle goes up and down, forming a continuous line of stitches.
It is the reciprocating motion of the pistons that is changed into rotary motion by the cam axle.
