... 3. The need to distinguish quantities that are purely numeric, i.e., scalars, from those physical quantities that require direction as well, i.e., vectors, may be developed by some rather simplistic demonstrations using tools such as a pair of rulers, especially if they are of different lengths.

... This occurs when the normal force goes to zero or, equivalently, when all the weight is used to achieve circular motion. Fc = mg = m v2 /r v = (gr)1/2 ½ (just like an object in orbit) ...

... Most candidates found something that they could do and quite a few could do most of the paper but there were several widespread difficulties. First there was a part question that very few could do: Q 7 (iii) proved inaccessible to most candidates, partly because the response we were looking for was ...

Inertial Forces and the Laws of Dynamics
... its acceleration is equal to the sum of all forces acting on the point. But this is completely wrong, because only the accelerating forces are presented on the right-hand side of Eq(3). Equation (3) itself expresses an equilibrium between the accelerating forces and the inertial force reflected on i ...

Phase velocity and group velocity
... In the following, we shall look at the difference of group velocity and phase velocity for a few situations associated with these different dispersions. In each case, we will study the propagation of waves with different values of k (and thus of ω). Then we form a package of such waves centered arou ...
