Motion blur - is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.

ISO - in Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds.
Aperture - A device that controls the amount of light admitted through an opening.
Shutter speed - the nominal time for which a shutter is open at a given setting.
Note:
The main f stops in your camera are 2.8,4.0, 5.6, 8,11,16,22, 32. for each increase in f stop value the amount
of light entering the camera is reduced by a half.
