Heat energy is the tr transf ansf ansfer er of thermal energy energy.. 3. Complete the sentence: The faster the molecules move, the higher the temper temperature. ature. 4. What is solar energy? Solar energy is the energy fr from om the Sun, whi which ch provides heat and llight ight energy for Earth. 5. What is a solar cell? Solar cells can be used to con convert vert solar energy to electrical energy energy.. n particles of 6. What is chemical energy? Chemical energy is energy stored iin matter matter.. 7. What are the 3 sources of chemical energy? Chemical energy can be found in bat batteries teries or food or anyth anything ing that burns. 8. What is electrical energy? Electrical energy is the energ energy y flowing in an electric circuit. 9. What are the 4 sources of electrical energy? 1) stored chemical energy iin n batteries 2) solar energy in solar ccells ells 3) hydro hydroelectric electric power plants 4) coal burning power plants 10. What is mechanical energy? Mechanical energy is the energy d due ue to the motion (kinetic) and position (po (potential) tential) of an object. 11. What are the 2 types of mechanical energy? potential and kinetic energy.. 12. What is potential energy? Mechanic Mechanical al Potenti Potential al energy is stored energy Mechanical potential energy is related to the position of an object. Examples: A stretched rubber b band and has potential energy energy.. W Water ater behind a dam has potential energy beca because use it can fal falll down the dam. object ject 13.
