FORMS OF ENERGY 7.Nuclear – Examples: Sun’s EnergyNuclear Power Plant
WHICH FORM OF ENERGY IS REPRESENTED IN EACH PICTURE?
SIMPLE ENERGY CONVERSIONS A change from one form of energy to another is called an ______________. Any form of energy can be converted Into any other form of energy.
ENERGY CONVERTING FROM POTENTIAL TO KINETIC MAX PE. MAX KE. MAX PE.
CHEMICAL ENERGY CONVERSIONS 1. Chemical energy 2. Mechanical energy 3. Heat Chemical mechanical thermal (heat)
Examples of Other Chemical Energy Conversions 1.Batteries(chemical) 2.Gas(chemical) Chemical to ?
Electrical Energy Conversions All electrical appliances are converting electricity. Name several examples of electrical conversions.
MECHANICAL ENERGY CONVERSIONS Movement causes friction which causes heat. Mechanical can turn into mechanical again. Bike: mechanical mechanical thermal sound
THERE HAS TO BE AN ENERGY CHANGE TO MAKE THINGS HAPPEN! ENERGY CONVERSIONS
CONSERVATION OF ENERGY The Law of Conservation of Energy states Energy cannot be Created or Destroyed.
Energy Resources – a natural resource that can be converted into energy for use by humans. Two Types of Energy Resources: Renewable & Nonrenewable
Renewable Resource – an energy resource that can be replaced in a short amount of time.
Renewable Resources: 1.Hydropower 2.Wind 3.Geothermal 4.Biomass 5.Solar power
Nonrenewable Resources – cannot be replaced after use or takes millions of years to replace. Fossil Fuels – energy resources that are formed from plants and animals that lived millions of years ago
Non Renewable Resources: 1.Coal 2.Natural Gas 3.Petroleum 4.Propane 5.Uranium
COMPLEX ENERGY CONVERSIONS Converting energy from the sun to make it available for use at your home.
Complex Energy Conversions All energy originates (starts) with the SUN!!!! HOW CAN WE MAKE ENERGY FROM THE SUN USEABLE???? The energy conversions involved with the sun are: How can we use the light energy given from the sun on earth?
