Want this question answered?
it is a vibration :)
A repeated cycle of a tuning fork.
Because of the friction from repeated motion and the molecules are being stretched to the limit of separation, therefore creating heat.
A simple harmonic motion is one for which the acceleration of the body into consideration is proportional its displacement from the mean position and the direction of the acceleration is always directed towards that mean position. It can be shown that, provided that the amplitude of oscillation is small, the motion of a simple pendulum is simple harmonic. All simple harmonic motions follow one rule F=-kx . When the oscillation is small(around 5 °), the motion of simple pendulum is simple harmonic motion.
No,the motion of heartbeat is non-periodic as when heart beats at 72 times per minute,then the heart once in 1 second and when heart beats at 144 times per minute,the heart beats once in 0.5 second,thus making the motion of the heart non-periodic.

Electrons are subatomic particles. Since electrons exhibit wavelike repeated motion, they tend to follow the same path around an atom.
A repeated cycle of a tuning fork.
Repetitive motion means the action is repeated again after a brief period of time where as periodic motion means it repeats after a fixed period of time.
I am guessing that it is Simple Harmonic Motion.
Repeated motion of a joint, such as during swimming, can cause tendonitis. See related link.
Dutch roll is a side to side and wing up, wing down repeated motion. Not a full roll.
This word is use when person is known or suspected to be lying. Often accompanied with a repeated flicking of the ear motion.
A human body regulates its temperature by sweating and shivering. When the body is too hot, glands produce sweat which contains heat and evaporates, taking the heat with it. When a human is too cold, the body starts to shiver, a quick, repeated motion which generated heat from repeated muscle motion.
