Aligned to the science curriculum, this stimulating volume explores mechanics by examining measurement, mass and weight, falling objects, force and acceleration, stability and equilibrium, energy, vectors and scalars, work and power, loads and levers, inclines and friction, and pulleys and gears. The text concludes with a chapter on Nicolas Copernicus, who developed the heliocentric model of the universe. Colorful diagrams explain difficult concepts and the workings of machines.
