• Used Book in Good Condition

When you are sitting still in a chair, what forces are at work? What happens if you tilt the chair on its back legs, or if ten people sit on your lap? How do the forces change? It is easy to see forces at work in a football game or at a theme park, but forces and motion happen in your daily life all the time without you even realizing it. Well-known science writers Alvin and Virginia Silverstein and Laura Silverstein Nunn explain different types of forces, how forces and simple machines work, the laws of motion, and how the laws act in different substances. The authors also reveal current research on forces and motion, showing ways that scientists and engineers are using this knowledge to improve almost every part of our modern lives.
