4 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?______________________potentialkineticThe energy of motionmassvelocity (speed)increases2(Mass x velocity ) x 1/2quadrupleEnergy that is stored and held in readiness.Elastic potential energygravitational potential energy
5 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 energytrueEnergy of movementheatenergy of moving electronsEnergy stored in chemical bondsEnergy that travels in waves such as light, sound, & microwavesEnergy from atoms splitting or joining together.2Potential & kineticKinetic + potentialjoulestrue
6 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 energychemicalNuclear energyShare your examples of the different forms of energy with your group.If you don’t agree with each other, discuss why.

8 the ability to do work Moves cars & boats, GlossaryEnergy:__________________________________________________________________________________________________________________Energy FactsReadEnergy 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 workMoves cars & boats,bakes a cake, keeps ice frozen, runs the radio & lights, makes us grow, helps us think…

10 VocabularyPotential Energy – stored energy of an object when it is NOT moving.Kinetic Energy – energy that an object has while it IS moving.Energy – the ability to do workChemical Energy – energy that is stored in chemical bonds of food & fuelThermal Energy – energy in the form of heatNuclear Energy - energy released by splitting atoms or fusing them together.
11 Vocabulary (On Worksheet) Energy – the ability to do _____________Potential Energy – ____________ energy of an object when it is ____________ moving.Kinetic Energy – energy that an object has while it _________ _________________.Chemical Energy – energy that is stored in _____________ & _______________Thermal Energy – energy in the form of ______Nuclear Energy - energy released by splitting ______________ or fusing them together.Foundational
