Open the data from Trials I, II, and III. Answer the following questions in Notes on your handheld computer.
Trials I and II are examples of Newton 's famous assertion that "for every action, there is an equal and opposite reaction." Does it seem to be true in both cases? Is the result surprising?
If you were pushing on each other with Force probes instead of pulling, would they still read the same?"
If one of the Force probes were attached to a wall and you were pulling on the other one, would they read the same force?
If a light cart hit a heavy cart at rest, what would you say now about the force on each one and their speeds after the collision?
Newton's Second Law asserts that a force is needed to change the velocity of an object. The greater the force, the more quickly the velocity changes. Describe an experiment to test this theory.
