Question

WHAT DO U MEAN BY PERIODIC MOTION AND REPETITIVE MOTION.......?​

Answer 1

Answer:

• Periodic motion is any movement of an object that repeats itself over a given length of time. We call the time it takes for the movement to repeat itself the time period, which we measure in seconds. Frequency, or the number of repetitions occurring each second, is measured in hertz.

• Repetitive motion disorders are a large group of conditions that primarily affect the soft tissues, including the nerves, tendons, ligaments, and muscles. Repetitive motion disorders include a family of muscular conditions that result from repeated motions performed in the course of normal work or daily activities.

Answer 2

Periodic motion

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

Repetitive motion

A term used to describe damage and pain caused by repetitive movement and overuse.

Repetitive strain injury impacts muscles, nerves, ligaments and tendons. These types of injuries can be caused by improper technique or overuse. The elderly are most commonly affected.
