08 2.3 Physics and mathematics
Physical quantities are linked by equations. An equation is a short, exact way of describing a physical relationship, and every equation carries a physical meaning. For example, v = d/t does not only say "divide d by t": it says that speed is the rate at which distance is covered. Always ask yourself what an equation means, not just how to substitute in it.
