5 Period 2 Activity Sheet Solutions: Forms of Energy 2.1 How are Forms of Energy Defined? Your instructor will discuss the forms of energy that we will study in the World of Energy. Give an example of each form of energy listed below. a) Mechanical Energy of Motion Energy exhibited by objects in motion. Example: any moving object. b) Thermal Energy Unorganized energy of motion exhibited by vibrations of atoms and molecules. Example: Example: rub hands together. c) Sound Energy Organized energy of motion exhibited by vibrations of atoms and molecules. Example: any sound. d) Electrical Energy Energy resulting from the forces between charged particles. Example: Electrical energy from a hand-cranked generator lights a bulb. e) Magnetic Energy Energy resulting from the forces between magnets, causing the magnets to attract or repel. Example: one magnet floats above another magnet. f) Radiant Energy Energy resulting from the vibrations of charges, such as radio waves, microwaves, light rays, and X-rays. Example: radiant energy from a floodlight shining on a solar cell powers the free play radio. g) Gravitational Potential Energy Energy stored in raised objects, which have the potential to fall. Examples: water wheel or any raised object. h) Strain Potential Energy Energy stored in stretched or compressed objects, such as springs. Examples: music box and wind-up toys. i) Electrical Potential Energy Energy stored in the separation of static (not moving) electric charges. Example: capacitor j) Chemical Potential Energy Energy available in the chemical bonds between atoms or molecules. Example: battery k) Nuclear Energy Energy available in the nucleus of atoms that can decay. Examples: smoke detector, the Sun
