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

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.
