Newton`s First Law of Motion
... As a result of his experiments, Galileo claimed that a stationary object tends to stay at rest and a moving object tends to keep moving. Inertia is defined as that property of an object that resists changes in its state of rest or motion. All objects possess inertia. For example, a stationary curlin ...

... Sample Problem – 3rd Law A tug-of-war team ties a rope to a tree and pulls hard horizontally to create a tension of 30,000 N in the rope. Suppose the team pulls equally hard when, instead of a tree, the other end of the rope is being pulled by another tug-of-war team such that no movement occurs. ...

Adding parallel vectors is usually not too much of a problem, but even antiparallel (a word which the students are not likely to know) vectors present problems. Another confu ...
