Mechanical Energy - Answer: Examples of this type of energy are water, wind, sound, blood flow, and walking. Heat Energy - Answer: This type of energy causes changes in temperature and phase. Kinetic Energy - Answer: Energy of Motion. Potential Energy - Answer: Energy of Position. Potential Energy - Answer: This type of energy is stored when work is done to it. Potential Energy - Answer: At the top of the arch, the ball has this maximum type of energy. Kinetic Energy - Answer: As the ball falls it gains this maximum type of energy. Volt - Answer: The amount of work done in moving electrons between two points. How fast. Electrical Charges - Answer: The result of something being given an amount of electrical energy. Alternating Circuit - Answer: An electric current that changes direction in an electric circuit. AC Charging - Answer: A neutral object acquires an electrical charge when it either gains or loses electrons. Electric Discharge - Answer: Loss of static electricity as changes move off an object. Magnetic Force - Answer: The force that causes two magnets to push or pull each other when their ends are brought together. Series Circuit - Answer: A circuit in which all the parts are connected one after another. Electrical Field - Answer: A region of space around an electrically charged object in which electrical forces on other charged particles are noticeable. Electric Circuit - Answer: A complete path, whicha allows electrons to move from high to low. Static Electricity - Answer: The build up of electrical charges on an object and they do not flow. Direct Circuit - Answer: An electric current that flows in one direction in an electric circuit. DC Resistance - Answer: All conditions which limit the flow of electrons inan electric circuit. Wave - Answer: A disturbance caused by energy moving from one place to another in a substance. Longitudinal Wave - Answer: A wave in which particles vibrate back and forth in the direction of the wave. Transverse Wave - Answer: A wave in which the molecules vibrate at right angles to the direction of the wave. Speed - Answer: How fast a wave travels. Refraction - Answer: The bending of a wave due to the change in its speed. Reflection - Answer: The bouncing of a wave off a barrier that does not absorb all the energy of the wave. Frequency - Answer: The number of complete waves thar pass a given point in one second. Hertz - Answer: Unit of measurement that is one complete wave passing a given point each second. Speeds up - Answer: If a wave passes from high density to low density it Slows down - Answer: If a wave passes from low density to high density it Products - Answer: As a result of an endothermic reaction, what has more energy?
