All of the above<\/strong><\/p>\n<p>The time of collision is the duration of the physical contact between two objects.

The period of impact is the time interval between the initial contact of the two objects and the time when the relative velocity of the two objects is zero.<\/p>\n<p>In general, the time of collision, the period of collision, and the period of impact are all the same.
