Section 1: ON THE MOVE
... The instantaneous speed of a moving object is estimated by measuring the distance the object travels in a very short time - Much less than 1 second. The smaller the measured time, the better will be the estimate for the object's instantaneous speed. For times longer than about 0.005 seconds, the spe ...

In what ways do forces affect an object`s motion?
