Describing motion | ||||||

Titles in the Physical World series |
Describing motion concerns the quantative description of a variety of physically important motions. Starting with simple examples of motion along a line, key concepts, such as position, velocity and acceleration are introduced and expressed using the fundamental rules of differential calculus. A study of projectile motion is used to generalize the discussion to two and three dimensions and to introduce the important idea of a vector. The descriptive power of calculus and vectors is then illustrated by studying a variety of repetitive periodic motions, including the circular motion of communications satellites, the simple harmonic motion of pendulums and mechanical oscillators, and the elliptical orbits of planets and space probes.
