Warm - up• What temperature on the Celsius

scale is equivalent to 373K?

• Which temperature is colder 0 F or 200 K?

Page 3: Kinds energy

What is Energy?

Different Kinds of Energy

Page 4: Kinds energy

What is Energy?

•The ability to do work.

Page 5: Kinds energy

Can you make things move?

•Then you have energy…

•…but there are seven different kinds of energy…

Page 6: Kinds energy

Chemical Energy

•What holds atoms in molecules together

•Can be released by chemical reactions like burning wood

Electrical Energy

•The movement of electrons through matter

•Electricity is a form of electrical energy

Heat Energy

•The random motion, or vibration, of atoms in matter

•The faster the atoms vibrate the more heat energy they have

Light Energy

•The vibrations of electrically charged particles

•Yes, whenever you are looking at light, you are looking at energy

Mechanical Energy

•Total energy of motion and position of an object

•ME=PE+KE•When you ride a bike you use mechanical energy

Nuclear Energy

•Holds protons and neutrons together in an atom’s nucleus

•Powers the sun and nuclear power plants

Sound Energy

•Vibrates air molecules•The air molecules move tiny bones in your ear

•The message of sound then moves to your brain

•Can also vibrate objects

Energy can be changed from one form to another

•Chemical energy in gasoline is changed to heat energy and then to mechanical energy in a car

•Law of Conservation of Energy

Gravitational Potential Energy

• Gravitational potential energy= weight x height

• Measured in Joules (J)

• Gravity = 1
