Newton`s Law Concept Test
... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backward) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wha ...

what happens when an object changes direction
... have just learned that a change in direction in one dimension, i.e a reversal, is associated with changing motion. Many of our experiences with motion involve a change in direction away from a straight line. If a change in direction is a change in motion, i.e. non-uniform, then a force (or unbalance ...
