2.5 Sodium (Na), chlorine (Cl) and potassium (K)

The element sodium is a soft silvery metal and the element chlorine is a greenish gas that is poisonous to humans and many other animals. Yet when these two elements are combined together in a compound called sodium chloride, the properties are quite different. Sodium chloride in its solid form is composed of white crystals and we call it salt. When salt dissolves in water, the constituent sodium ions, Na+, and chloride ions, Cl , become separated. Both of these ions

3.5 Velocity-time and speed-time graphs

Just as we may plot the position-time graph or the displacement-time graph of a particular motion, so we may plot a velocity-time graph for that motion. By convention, velocity is plotted on the vertical axis (since velocity is the dependent variable) and time (the independent variable) is plotted on the horizontal axis. In the special case of uniform motion, the velocity-time graph takes a particularly simple form - it is just a horizontal line, i.e. the gradient is zero. Examples are

2.2 Pressure in the atmosphere

The sounds we hear generally consist of rapid fluctuations of air pressure in the atmosphere that surrounds us. Sound can also be transmitted through other media, for instance water, so not all sound consists of fluctuations in air pressure. However, for the purposes of this discussion I shall confine myself to sound in air.

These fluctuations in air pressure are caused by a local disturbance to the air pressure, which might be sudden and transient – for example, when a paper bag is b

3.7 A note on straight-line graphs and their gradients

We end this section by reviewing some of the important features of straight-line graphs, though we do so in terms of two general variables z and y, rather than x and t, in order to emphasise their generality. If the graph of z against y is a straight line of the kind shown in Figure 22, then z and y are related by an equation of the form

Speaker(s): Ned Beauman, Dr Kate Devlin, Professor Nicholas Humphrey | While social psychologists and cognitive scientists affirm that minds do not exist separated from biological and social systems, our human utopias have always dreamt of a disembodied, free-floating consciousness.
