What are the different forms of energy?

  Energy makes change possible.  We use it to do things for us.  It moves cars along the road and boats over the water.  It bakes a cake in the oven and keeps ice frozen in the freezer.  It plays our favorite songs on the radio and lights our homes.  Energy is needed for our bodies to grow and it allows our minds to think. Why study energy?

  Energy : the ability to do work  Energy has a number of different forms, all of which measure the ability of an object or system to do work on another object or system.  In other words, there are different ways that an object or a system can possess energy. What is Energy?

(page 1 in Notes Section of Binder)

 Potential (PE) Kinetic (KE) Types of Energy aka: Stored energy Definition: Energy that an object or substance has because of its position or condition. aka: released energy Definition: The energy of motion in the form of waves, electrons, atoms, molecules, and substances.

(Page 2) Energy is the ability to do work. Potential EnergyKinetic Energy Stored Energy Not Moving Increases based on position or height. Examples: top of roller coaster, tree branch about to fall Energy in Motion Increases as motion increases Examples: car driving fast, a motor spinning, person running Types of energy Transforms into other forms of energy

(Page 3) Cut out the picture and glue to page 3 in your notebook. Color each roller coaster car a different color.

 Roller Coaster PE & KE  Point A  Mostly potential energy  Sitting at the top of the hill.  Point B  Losing potential energy and gaining kinetic energy.  Moving down the hill

  Point C  Mostly kinetic energy  Bottom of hill, reaching highest speed.  Point D  Losing kinetic energy and gaining potential energy.  Slowing down as it goes up the hill. Roller Coaster PE & KE

 Forms of PE & KE

  There are four types:  Chemical Energy  Nuclear Energy  Stored Mechanical Energy  Gravitational Energy Potential Energy

  The energy stored in the bonds of atoms and molecules.  Examples: Food, Biomass, petroleum, natural gas, propane, and coal Chemical Energy

  The energy stored in the nucleus of an atom—the energy that holds the nucleus together.  Example: The energy in the nucleus of a uranium atom. Nuclear Energy

  Energy stored in objects by the application of force.  Examples: Compressed springs and stretched rubber bands Stored Mechanical Energy

  The energy of place or position.  Examples: Water in a reservoir behind a hydropower dam, roller coaster at the top of the hill. Gravitational Energy

  Radiant Energy  Thermal Energy  Motion  Sound  Electrical Energy Kinetic Energy

  Electromagnetic energy that travels in waves or particles.  Examples: sunlight and solar energy Radiant Energy

  The vibration or movement of atoms and molecules in substances.  Examples: heat, Geothermal energy Thermal Energy

  The movement of a substance from one place to another.  Examples: Wind, hydropower, person running Motion

  The energy associated with the vibration or disturbance of matter.  Examples: Voices, horns, bells, screams Sound

  The movement of electrons  Examples: Lightning and electricity Electrical Energy

 Energy Doesn’t Disappear  Law of Conservation of Energy - Energy is not created nor destroyed, only transformed.
