Paul Andersen explains how objects interact when touching and at a distance. Electromagnetic forces are very important when objects are touching and fields explain both electromagnetic and gravitational forces. The strong and weak nuclear forces can result in radioactive decay. A brief description of Newton's Law of Universal Gravitation and Coulomb's Law are includes. A teaching progression from grades K-12 is also included.
