1. Warm up: You set off a bottle rocket that has 200 J of chemical potential energy. Activity 58: Follow the Energy What types of energy can the chemical potential energy transform into? If all of the energies that it transformed into are equal, how many joules should each type have?

2. The Law of Conservation of Energy states that energy cannot be created or destroyed, but rather transformed or transferred. The total amount of energy used in a system or scenario never changes, instead it changes form. ◦ If a car has 100 J at the top of a hill, it will still have 100 J at the bottom of the hill. It will just be a different type of energy. (Potential  Kinetic/Thermal/Sound) Activity 57 In Case You Missed It…

13. Please open your books to page D32. Activity 58: Follow the Energy

14. Read the procedure with your group on page D33. Instead of getting 8 cards like the book says, you are getting 12. When you are finished, you can work on the first analysis question. Activity 58: Follow the Energy

15. Chemical potential energy- energy stored in bonds of atoms and molecules. ◦ Energy stored in food before you digest it. Elastic potential energy- energy stored by stretching or compressing. ◦ Energy stored in a stretched rubber band. Energy Types: Potential Energies

16. Gravitational potential energy - energy stored due to an object’s weight and height. Energy Types: Potential Energies

17. Electric energy (current)- movement of a charge and energy from one place to another. ◦ Electricity through wires. Light energy- energy transferred by rapid movement of electromagnetic fields. ◦ Energy transferred by sunlight or X rays. Motion (kinetic)- movement of an object from one place to another. Energy Types: Kinetic Energies

18. Sound energy- energy transferred by the vibration of an object. ◦ Music, voices, etc. Thermal energy- energy transferred from hot to cold objects. ◦ Hot plate heating hot water Energy Types: Kinetic Energies
