EQ: Can I recognize different types of energy transformations?

3. Nature of Energy Energy is all around you!
You can hear energy as sound.
You can see energy as light
You can feel energy as wind

4. Nature of Energy You use energy when you: Hit a softball
Life your book bag
Compress a spring

5. Nature of Energy
Living Organisms need energy for growth and movement.

6. Nature of Energy Energy is involved when: A bird flies A bomb explodes
A rain falls from the sky
Electricity flows through a wire

7. What is energy that it can be involved in so many different activities?
Energy can be defined as the ability to do work.
If an object or organism does work (exerts a force over a distance to move an object) the object or organism uses energy.

8. Forms of Energy The five main forms of energy are: Heat Chemical
Electromagnetic
Nuclear
Mechanical

9. Heat Energy
The internal motion of the atoms is called heat energy, because moving particles produce heat.
Heat energy can be produced by friction.
Heat energy causes changes in temperature and phase of any form of matter.

10. Chemical Energy Chemical Energy is required to bond atoms together.
And when bonds are broken, energy is released.

11. Chemical Energy
Fuel and food are forms of stored chemical energy.

12. Electromagnetic Energy
Power lines carry electromagnetic energy into your home in the form of electricity.

13. Electromagnetic Energy
Light is a form of electromagnetic energy.
Each color of light (ROY G BV) represents a different amount of electromagnetic energy.
Electromagnetic Energy is also carried by X-rays, radio waves, and laser light

14. Nuclear Energy
The nucleus of an atoms is the source of nuclear energy.

15. Nuclear Energy
When the nucleus splits (fission), nuclear energy is released in the form of heat energy and light energy.
Nuclear energy is also released when nuclei collide at high speed and join (fuse).

16. Nuclear Energy
The sun’s energy is produced from a nuclear fusion reaction in which hydrogen nuclei fuse to form helium nuclei.

17. Nuclear Energy
Nuclear energy is the most concentrated form of energy.

18. Energy can be transferred, or converted, from one form to another!
Forms of Energy
Mechanical
Thermal
Chemical
Electrical
Electromagnetic
Nuclear
Energy can be transferred, or converted, from one form to another!

19. Energy associated with the motion of an object.
Mechanical Energy
Energy associated with the motion of an object.
Rest + Motion
Chewing
Sound
Frog Dancing

20. Mechanical Energy
When work is done to an object, it acquires energy. The energy it acquires is known as mechanical energy.

21. When you kick a football, you give mechanical energy to the football to make it move.

22. When you throw a bowling ball, you give it energy
When you throw a bowling ball, you give it energy. When that bowling ball hits the pins, some of the energy is transferred to the pins (transfer of momentum).

23. Total energy of the particles in a substance or material.
Thermal Energy
Total energy of the particles in a substance or material.
All objects give off thermal energy
Ice cream melting gains thermal energy

24. Potential energy stored in chemical bonds.
Chemical Energy
Potential energy stored in chemical bonds.
Food
Fire Cracker
Stomach
Battery

25. Moving electrical charges that produce electricity and energy.

Static Shock
Lightening
Computers/TVs/Radios
Lights

26. Electromagnetic Energy
Energy that travels in waves
Visible light
UV Rays
Microwaves

27. Electromagnetic Energy
Light Energy

28. Energy stored in the nucleus of an atom from fission or fusion
Nuclear Energy
Energy stored in the nucleus of an atom from fission or fusion
Sun
Stars
Nuclear Power Plant

29. Law of Conservation of Energy
Energy can NOT be created or destroyed, only transformed from one form to another.
With every energy transformation some energy is always given off as heat energy.

30. In 1905, Albert Einstein said that mass and energy can be converted into each other.
He showed that if matter is destroyed, energy is created, and if energy is destroyed mass is created.

31. Energy Conversion
Energy can be changed from one form to another. Changes in the form of energy are called energy conversions.

32. Energy Conversions
All forms of energy can be converted into other forms.
The sun’s energy through solar cells can be converted directly into electricity
Green plans convert the sun’s energy (electromagnetic) into starches and sugars (chemical energy).

33. Other energy conversions
In an electric motor, electromagnetic energy is converted to mechanical energy.
In a battery, chemical energy is converted into electromagnetic energy.
The mechanical energy of a waterfall is converted to electrical energy in a generator.

34. In an automobile engine, fuel is burned to convert chemical energy into heat energy. The heat energy is then changed into mechanical energy.
