What is reciprocating motion definition?

Reciprocating motion refers to a back-and-forth movement of an object or body in a straight line. In this type of motion, the object moves in one direction, then reverses its motion and moves back in the opposite direction. This type of motion is often seen in piston engines, where the piston moves back and forth within a cylinder, generating power and propelling the engine. Other examples of reciprocating motion include the movement of a sewing machine needle, the stroke of a saw blade, and the motion of a pendulum. Reciprocating motion is used in many mechanical devices, and understanding it is important in the design and operation of machines and mechanisms.
