1. THE NATURE OF ENERGY

2. Energy Is the Ability to Do Work Work involves motion

3. Is this guy working?

4. Why is he sweating?

5. Work happens when a force moves an object over a distance! Who is working?

6. Potential Energy in motion Stored energy (the potential to do work is there but not seen) Kinetic

8. The amount of mass and velocity there is determines how much Kinetic Energy there is

9. Mass then Kinetic Energy Velocity then Kinetic Energy Kinetic Energy = mass x velocity 2 2

11. Mechanical Heat or Thermal Electrical Electromagnetic Chemical Nuclear

12. Mechanical Energy energy that is possessed by an object due to its motion or due to its position can be either kinetic energy (energy of motion) or potential energy (stored energy of position)kinetic energypotential energy Ex. A moving car possesses mechanical energy due to its motion Ex. A barbell lifted high above a weightlifter's head possesses mechanical energy due to its vertical position above the ground

13. An object that possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy - whether it is in the form of potential energy or kinetic energy - is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be moved.potential energykinetic energy Mechanical Energy is defined as the Ability to Do Work

14. Comes from moving electrical charges in the atom (electrons) Seen as power lines, batteries, lightening, and static electricity

15. Potential energy that is stored as chemical bonds holding together chemical compounds Examples are chemical batteries, candles (wax), and food in our bodies

17. Travels in waves Is a combination of magnetic and electrical waves Examples include light, microwaves, x-rays, radiation, and radio waves

19. Heat or Thermal Can be Kinetic or Potential Comes from energy inside atoms and molecules As the atoms or molecules move faster, the thermal energy increases

21. Energy stored in the nucleus of an atom Results when the nucleus splits or joins with another nucleus Can happen naturally, from a star, or manmade, from a nuclear power plant

23. Energy can be transformed from 1 form to another, especially from potential to kinetic Examples include: The electrical energy from a power line causes a motor to run which creates wind, which travels in waves A wax candle creates heat which travels in waves and can turn a fan
