1. Energy is the ability to do WORK (or move things)

2.  Energy is measured in JOULES  Energy that is stored is called POTENTIAL  The energy of moving things is called KINETIC  An example of when potential energy is transferred into kinetic energy is when

3.  Mechanical energy is the energy of motion (when whole objects move, like when CARS move).  THERMAL energy causes the movement and vibration of atoms and molecules. (Motion of atoms and molecules)  The more energy, the MORE these tiny particles move.

4.  Electromagnetic Energy or Radiant Energy involves the movement of PHOTONS of various WAVELENGTHS, like visible light, X- rays, radio waves, microwaves, etc.

5.  CHEMICAL energy is stored in substances like food, batteries, or fuel (like gas, oil, diesel or kerosene.)  NUCLEAR energy is the energy trapped in the NUCLEUS of an atom due to the forces of the nucleus like STRONG nuclear FORCE.  GRAVITATIONAL energy is the potential to do work and set objects into motion created by gravity.

6.  When you eat food then the energy is used by muscles, CHEMICAL energy that has been turned into MECHANICAL energy.  When you turn on a fan, energy is turned from ELECTRICAL energy into MECHANICAL energy.  A solar panel turns RADIANT energy into ELECTRICAL energy.  Burning coal in a power plant turns CHEMICAL energy into THERMAL energy.

7.  Calories and calories are two units of energy. 1 Calorie = 1,000 calories A Calorie is a Food Calorie and it is the amount of energy to raise one kilogram of water one degree Celsius.  Joules 1 calorie = 4.184 J or 1 Calorie = 4,184 J  Conversion

8.  If you have 100 Calories, how many calories and Joules do you have?  100 Calories x 1,000 calories = 100,000 cal 1 Calories  100 Calories x 4,184 Joules = 418,400 J 1 Calories

9.  Temperature is measuring the MOVEMENT of matter.  Fahrenheit - °F  Celsius - °C  Common Temperatures in Celsius and Fahrenheit

11.  3500 Calories = 1 pound  If Calories are not used they are stored as fat.  If Calories are used, then the body must use stored fat.

12.  These organic compounds are what make up every living thing.  We are composed of these and we eat these to make us.  All 3 of these have calories.  Carbs provide energy, protein provides structure, and fats provide storage and energy.

13.  Hour running on treadmill = 600 Calories  Hour of ballet or tap dancing = 300 Calories  Hour on elliptical = 500 Calories  Hour of rock climbing = 700 Calories  Hour of swimming = 700 Calories  A 150 lb person burns 1800 Calories per day from regular activities:  Rule of 12: 150 x 12 = 1800

18.  Monster = 200 Calories  Eggo Waffle = 100 Calories  Donut = 300 Calories  Quarter Pounder = 500 Calories  Medium French Fries = 400 Calories  Coffee = 0 Calories  Water = 0 Calories  Coke Zero = 0 Calories  Pack of Peanut M&M’s = 150 Calories

20. 1) What is chemical potential energy?  A) energy of motion  B) energy stored within a bond  C) energy stored due to an objects position  D) energy produced by a chemical reaction. 2) Give an example where chemical potential energy is found.
