TO DO Waves, which exist in mechanical and electromagnetic forms, have various properties. Vibrations in materials set up wave like disturbances that spread away from the source. Other things that give off or reflect light have a different mix of colors.
Forces affect motion in a variety of ways.
A. Newton's Laws 1. An unbalanced force acting on an object changes its speed or path of motion, or both. If the force acts toward a single center, the object's path may curve into an orbit around the center. B. Gravitational Force and Motion not addressed at this grade level. C. Magnetic and Electric Forces 1.
