The ability to do work How things change and move molecules

The STORED energy an object has because of its position. The energy stored in an object based on its height and mass. The more mass and higher off the ground, the more gravitational potential energy an object has. The STORED energy an object has because of its position. Measured in joules (j)

Law of Conservation of Energy The energy an object has due to its motion. Seen as movement Law of Conservation of Energy from KE

Card Sort Time! Working with your shoulder partner, sort the cards into examples of Potential Energy and Kinetic Energy.

Potential Kinetic Energy of motion A bouncing ball A soccer player kicking the ball into the goal A bowling ball rolling down the lane A rubber band flying through the air A skier skiing down a snow-covered mountain A 9-volt batter on the kitchen counter A rock sitting on top of a hill An apple on a tree branch Stored energy A car parked in a parking lot A book sitting on a table

Energy Transformations: The change of energy from one form to another. Chemical Energy: Energy stored in chemical bonds and released through chemical reactions. Electrical Energy: A form of energy made available by the flow of electric charge through a conductor.

Radiant Energy: A form of energy that exhibits wave-like behavior as it travels through space; part of the electromagnetic spectrum. Mechanical Energy: The sum of the potential and kinetic energy of an object. Thermal Energy: The total kinetic (motion) energy of the tiny particles that make up matter. The faster the particles move, the warmer the matter becomes.

Sound Energy: A form of energy that is made by vibrations and requires a medium (such as air, water, or solids) in order to travel. Sound waves travel slower than light waves!

Card Sort Time! Working with your shoulder partner, place the cards/arrows in a manner that shows the flow of energy transformation.

Plants, animals, microorganisms, and humans consume sugar molecules created by photosynthesis. Organisms that move transform this chemical energy into mechanical energy. The Sun transforms nuclear energy to electromagnetic energy, which travels to Earth as light waves. Plants, algae, and some bacteria use photosynthesis to capture sunlight and use it to produce energy-rich sugar molecules. These molecules store lots of chemical energy in their bonds. Some organisms convert mechanical energy to thermal energy so that they can keep their body temperatures relatively stable. Plants and animals that died many millions of years ago store chemical energy, and over time their remains became coal. Power plants burn coal, releasing the stored chemical energy as heat, or thermal energy. Electrical energy travels through wires to provide power in homes, businesses, and institutions. Most devices transform the electrical energy into another form of energy. For example, a toaster transforms electrical energy into thermal energy. The thermal energy from burning coal generates steam, which turns a turbine inside of a power plant, thereby transforming thermal energy to mechanical energy. In the power plant, turbines spin electric generators, which transform mechanical energy to electrical energy.
