... Having considered motion confined to a line in the previous section, we now go on to consider motion confined to a plane. At any given instant in time the particle’s position relative to the origin of a coordinate system is denoted by r(t). At this same instant the particle is moving in the directio ...

Newton`s second law of motion
... Do they find that acceleration is proportional to force, and inversely proportional to mass? Numerically, are their results consistent with the equation F = ma? You may wish to point out that the experiment can only show proportionality. In other words, we can only conclude that F = kma, where k is ...
