lab 3: newton`s second law of motion
... Force can be defined as any influence that tends to change the motion of an object, and can be thought of as a push or a pull acting on an object. Mass is the measure of the inertia of an object. Inertia or mass relates to how difficult it is to start a resting object into motion, or alternatively, ...

Here we shall discuss only the Second Law, which states that the motion of an object is changed by forces in this way: the time-rate-ofchange of a quantity called momentum is proportional to the force. Let us explain the idea. Momentum is not the same as velocity. A lot of words are used in physics, ...
