So here we could say that his speed is 1 m/s but his velocity is 1 m/s towards the right. ( An aside for physicists: velocity is a vector, meaning that it has direction as well as magnitude. This means that, for each second he travels, his displacement from the starting position increases by 1 m. The strange man in this animation is moving in a straight line at a constant speed of one metre per second. The velocity is the rate of change of displacement. This page supports the Physclips project.ĭifferentiation: How rapidly does something change? What is a logarithm? A brief introductionĭifferential Equations: some simple examples (separate page).Integration: How do the results of a variable rate add up?.Differentiation: How rapidly does something change?.This short introduction is no substitute, however, for a good high school calculus course: we shall take some short cuts of which mathematicians may disapprove. So stick with us: differentiation really is just subtracting and dividing, and integration really is just multiplying and adding. Fortunately, one can do a lot of introductory physics with just a few of the basic techniques. For physics, you'll need at least some of the simplest and most important concepts from calculus. Calculus analyses things that change, and physics is much concerned with changes. The basic ideas are not more difficult than that. The flow is the time derivative of the water in the bucket. Here's a simple example: the bucket at right integrates the flow from the tap over time. Calculus: differentials, integrals and partial derivatives.Ĭalculus – differentiation, integration etc.
