1 ENERGY BASICS PACKET Packet Includes: I. Objectives II. Energy Reading III. Energy Notes IV. Review Questions 1-7 & (answer on separate sheet) V. Quiz Review I. Unit Objectives: 1. Students will be able to define, correctly use, and provide examples of the following terms: Energy Kinetic energy (KE) Potential energy (PE) Mechanical energy (ME) Other types of Energy: Thermal energy Chemical energy Electrical energy Sound energy Light energy Nuclear energy Energy transfer / conversion Conservation of energy 2. Students will be able to use a diagram or model of a moving object to describe the conversion of potential energy into kinetic energy and vice versa. 3. Students will be able to discuss different forms of energy and describe how they can be converted from one form to another for use by humans (useable energy). 4. Students will be able to explain the energy conversion that takes place in the human body once food enters.

Term Definition Examples Energy Kinetic (KE) KE = mv 2 2 energy m = mass, v = velocity Potential energy (PE) Gravitational PE = weight X height Mechanical energy (ME) ME = KE + PE Thermal energy The kinetic energy that all objects have due to the movement of the particles that make the object up. Depends on temperature and number of particles. Example: Ice has less thermal energy than steam.
7 Chemical energy Electrical energy Sound energy Energy caused by objects vibration Light energy Nuclear energy Food Energy Chemical energy that comes from the foods that we eat. Unit is calories (C) Food is digested, chemical energy from food transferred so body can perform its functions. Eat cereal, body digests cereal, the chemical energy from the cereal you eat is transferred so you can move. Unused energy is stored as fat.

13 V. Quiz Review 1. Terms / Definitions: Write the correct term next to the definition Term Definition the amount of work that an object can due because of the objects kinetic and potential energy or the energy with which moving objects perform work the ability to do work moving energy the energy of an object due to the objects motion The kinetic energy that all objects have due to the movement of the particles that make the object up. Depends on temperature and number of particles. Produced by flow of electrons through a conductor such as a wire the stored energy that an object has due to its position or chemical makeup. Energy that moves in waves caused by the vibration of electrically charged particles and can travel through a vacuum Chemical energy that comes from the foods that we eat. Energy stored in the nucleus of an atom, energy is released when nuclei join or split Energy caused by objects vibrations that travel through the air Energy stored in certain substances because of the make up of chemical bonds A change from one form of energy to another States that energy cannot be created or destroyed, but it can be transferred from one type if energy to other types of energy
