TYPES OF ENERGY Pg. 40-41 Warm up- How would you make your cell phone work if there was no electricity? Essential Question: Explain the different types of energy.
Different Types… There are many different types of energy. Some of them are: Radiant (from the sun) Electrical (electricity) Chemical (any chemical or compound) Thermal (heat energy) Nuclear (radioactive energy!!) Kinetic Potential **Today we’re talking about Kinetic & Potential Energy!!
Mechanical Energy o Energy due to a object’s motion (kinetic) or position (potential). o Example: o bowling ball o rocket o you The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!
Electrical Energy o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy o Examples o radio o chargers o computers
Chemical Energy o Energy from chemical reactions oExamples o Plants o Matches o Batteries The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.
Eletromagnetic Energy o light energy in the form of waves o Example: o cell phones o radios o x-rays o infrared Electromagnetic Energy comes from any item that emits gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
Thermal Energy o Heat energy o The heat energy of an object determines how active its atoms are. o Example: o boiling water o friction o fire A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.
QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY
QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy? MECHANICAL ENERGY
QUIZ TIME! What energy transformation occurs when an electric lamp is turned on? ELECTRICAL ENERGY ELECTROMAGNETIC ENERGY
