What is Energy: Textbook Guided Reading & Study: What are the 2 general kinds of energy? a. ____________________ b. __________________ What is kinetic energy? _______________________________________________ The kinetic energy of an object depends on both its _________________________ and its _____________________________________ Kinetic energy increases as velocity ____________________________________. What formula do you use to calculate kinetic energy? _______________________ Because velocity is squared in the kinetic energy equation, doubling an object’s velocity will __________________________ its kinetic energy. What is potential energy? _____________________________________________ What is the potential energy called that is associated with objects that can be stretched or compressed? _____________________________________________ What is potential energy called that depends on height?______________________ potential kinetic The energy of motion mass velocity (speed) increases 2 (Mass x velocity ) x 1/2 quadruple Energy that is stored and held in readiness. Elastic potential energy gravitational potential energy

Weight x height = gravitational potential energy true 13. What is the formula you use to determine the gravitational potential energy of an object? _________________________________ The greater the height of an object, the greater its gravitational potential energy? _________ FORMS OF ENERGY (**You may ADD these short definitions to your definitions) Mechanical Energy – Thermal Energy – Electrical Energy – Chemical Energy – Electromagnetic Energy – Nuclear Energy – What 2 forms of energy are associated with mechanical energy? ______________________ How would you calculate an object’s mechanical energy? __________________________ What SI unit is used to measure mechanical energy? __________________________ When the particles of an object move faster, it’s thermal energy increases? _____________ Weight x height = gravitational potential energy true Energy of movement heat energy of moving electrons Energy stored in chemical bonds Energy that travels in waves such as light, sound, & microwaves Energy from atoms splitting or joining together. 2 Potential & kinetic Kinetic + potential joules true

Share your examples of the different forms of energy with your group. What kind of energy do you experience when you get a shock from a metal doorknob? ___________________________________________ What kind of energy is stored in the bonds in compounds of the food you eat? ___________ What kind of energy is stored in the nucleus of an atom? __________________________ Electrical energy chemical Nuclear energy Share your examples of the different forms of energy with your group. If you don’t agree with each other, discuss why.

the ability to do work Moves cars & boats, Glossary Energy:__________________________________________________________________________________________________________________ Energy Facts Read Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favorite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. What are two things that energy does for us? _____________________ _________________________________________________________ Energy Organizer: Identify the two main forms of energy & fill in the types under each form. Include an example with each type! Example: radiant & gravitational energy is done for you. the ability to do work Moves cars & boats, bakes a cake, keeps ice frozen, runs the radio & lights, makes us grow, helps us think…

Chemical: biomass, petroleum, natural gas, propane Kinetic Potential Chemical: biomass, petroleum, natural gas, propane Electrical: lightning Stored mechanical: compressed spring, stretched rubber band Nuclear: nuclear power plants Thermal: heat Sound: vibrations Gravitational Energy: rock resting at top of hill Motion: wind

- What Is Energy? Kinetic Energy Kinetic energy increases as mass and velocity increases.

- What Is Energy? Potential Energy Gravitational potential energy increases as weight and height increase.

DISCOVERY EDUCATION Interactive VIDEO CLIP Five Main Forms of Energy

Vocabulary (On Worksheet) Energy – the ability to do work Potential Energy – stored energy of an object when it is NOT moving. Kinetic Energy – energy that an object has while it IS moving. Chemical Energy – energy that is stored in chemical bonds of food & fuel Thermal Energy – energy in the form of heat Nuclear Energy - energy released by splitting atoms or fusing them together.
