Energy Ability to do work
Vocabulary • 1. Potential energy • 2. Kinetic energy • 3. Wind energy • 4. Electrical • 5. Thermal energy • 6. Mechanical energy • 7. Chemical energy
KWL on Energy • Kinetic energy can not be more than potential energy- • There are multiple types of energy- • Without energy, the world could not function- • Electricity is a form of energy- • Kinetic energy comes from a body in motion- • Energy can be changed into different forms-
What is work? Done when a force moves an object
What is Kinetic Energy? Energy of MOTION
What is potential energy? Stored energy
What is solar energy? Most energy comes from the sun Energy from the sun!
What is chemical energy? Plants use the energy in sunlight to make food. Chemical energy is a form of potential energy used by food and fuels.
Energy can change from one form to another Remember the roller coaster? Remember the Bill Nye bowling ball? (smash) When wood burns, chemical energy stored in the wood changes to heat energy and light energy.
Did you know??? Energy can’t be created or destroyed. The same amount of energy exist before and after it changes form.
More about… Mechanical energy- the total energy of motion and position of an object Potential energy plus kinetic energy = mechanical energy
More about … Chemical energy – energy that can be stored and released by a chemical reaction. Example- car’s motor Electrical energy – energy caused by the movement of electrical charges. Example – anything that you can plug in
Information Tidbit… Did you know? What does EVERY living thing contain??? Carbon!!!
