Every event that occurs in the universe is governed by forces that are capable of acting at a distance, that is, no direct interaction among the objects is required. Gravity is the weakest of all forces, but the most pervasive because it is generated by all bodies that have mass. Electromagnetic forces which act between electrically charged particles are responsible for all chemical reactions and the most recognizable physical properties, such as heat and light. These forces along with those that control interactions within atoms are the fundamental forces that govern all known natural phenomena.Conceptual StrandEverything in the universe exerts a gravitational force on everything else; there is an interplay between magnetic fields and electrical currentsGuiding QuestionWhat are the scientific principles that explain gravity and electromagnetism?

Check For Understanding
Explain how two magnets interact.
Describe what happens when an object is dropped and record the observations in a science notebook.
