Principles of Exposure

Tracking Motion:

While tracking the item in motion with slow shutter speed we made the tracked item crisp while the background was blurred.

Object in Motion:

While keeping the camera really still and a slow shutter speed I made the object in motion blurred to exaggerate the object in motion causing it to blur.

Object Frozen in Time:

While tracking the item in motion with slow shutter speed we made the tracked item crisp while the background was blurred.
