<ul><li>Slide 1</li></ul> <p>Energy Notes Slide 2 What is the ability to cause a change in matter? energy energy Slide 3 What is the measure of how much work something can produce? energy energy Slide 4 What is work? Using force to move an object Using force to move an object Slide 5 Why is energy not a type of matter? Matter: Solid, liquid, gas Matter: Solid, liquid, gas Energy: Ability to move matter around Energy: Ability to move matter around Slide 6 What law states that energy can never be made or destroyed, but it can change forms? Law of Conservation of Energy Law of Conservation of Energy Slide 7 What do people use energy for? Use the energy stored in food to move, to talk, and even to sleep Use the energy stored in food to move, to talk, and even to sleep Slide 8 What is kinetic energy? Energy in motion Energy in motion Slide 9 Give an example of kinetic energy. Airplane flying Airplane flying Person riding a bike Person riding a bike Slide 10 What is potential energy? Energy an object has because of its condition or position Energy an object has because of its condition or position (stored energy) (stored energy) Slide 11 Give an example of potential energy. A ball sitting on a desk waiting to fall A ball sitting on a desk waiting to fall A book on a shelf waiting to fall A book on a shelf waiting to fall Slide 12 When can something have both kinetic and potential energy? As a book falls from the shelf, it loses potential energy and gains kinetic energy As a book falls from the shelf, it loses potential energy and gains kinetic energy Slide 13 What is the movement of energy from one place or object to another? Energy transfer Energy transfer Slide 14 Give an example of transferring energy? Throwing a basketball from yourself to your teammate, and then this person dribbles the ball. Throwing a basketball from yourself to your teammate, and then this person dribbles the ball. Slide 15 What is energy that comes from the Sun? Solar Energy Solar Energy Slide 16 What does solar mean? of the sun of the sun Slide 17 When do people use solar energy? Solar-powered calculators Solar-powered calculators Slide 18 Energy from the Sun travels as ____________. radiation radiation Slide 19 What are the two types of radiation? Light- We can see Light- We can see Heat- We can feel Heat- We can feel Slide 20 What would Earth be like without solar energy? Ball of frozen rock with no life Ball of frozen rock with no life Slide 21 How is solar energy useful? Electricity for some buildings Electricity for some buildings Heat water (swimming pools and home showers) Heat water (swimming pools and home showers) Slide 22 What are problems with solar energy? expensive expensive Many places do not have enough sunny days Many places do not have enough sunny days Slide 23 What is energy stored in fuel called? Chemical energy Chemical energy Slide 24 How can it be released, and what is it when it is not being used? By a chemical reaction (like burning) By a chemical reaction (like burning) When it is not being used it is potential energy When it is not being used it is potential energy Slide 25 Give an example of a chemical reaction. Burning wood Burning wood Slide 26 What energy is the combination of all the potential and kinetic energy that something has? Mechanical energy Mechanical energy Slide 27 Give an example of mechanical energy. Helicopter moving- Kinetic Energy Helicopter moving- Kinetic Energy Fuel in tank- Chemical Energy, which is potential Fuel in tank- Chemical Energy, which is potential The combining of both causes mechanical energy The combining of both causes mechanical energy Slide 28 What energy comes from an electric current? What is another name for it? Electrical energy Electrical energy Electricity Electricity Slide 29 Give an example of electrical energy. Slide 30 What is energy in the form of vibrations that travel through matter? Sound energy Sound energy Slide 31 Give an example of sound energy. Placing hands on radio and feeling the vibrations Placing hands on radio and feeling the vibrations Feeling the vibrations of sounds with their feet Feeling the vibrations of sounds with their feet Slide 32 What is thermal energy? Heat energy Heat energy Slide 33 What is the transfer of thermal energy between objects with different temperatures? Heat Heat Slide 34 How does thermal energy travel? From warmer objects to a cooler object From warmer objects to a cooler object Slide 35 What is transferred when you hold a hot mug? Thermal energy goes from cup to your hand Thermal energy goes from cup to your hand Slide 36 What is lost from the same mug when you hold it? Energy is lost in the mug and transferred to your hands. Energy is lost in the mug and transferred to your hands. Slide 37 What is the measurement of the average kinetic energy of all the particles in a substance? Temperature Temperature Slide 38 What is the most common way to produce heat by rubbing things together? Friction Friction Slide 39 Give an example of friction. Rubbing your hands together Rubbing your hands together Slamming on the cars brakes Slamming on the cars brakes Slide 40 What is a set of parts acting together as a whole object? System System Slide 41 Give an example of a system. A burner, a pot, and water are a system that produces thermal energy. A burner, a pot, and water are a system that produces thermal energy. Slide 42 What is transfer of thermal energy from one object directly into another? conduction conduction Slide 43 Give an example of conduction. Holding a hot mug Holding a hot mug Slide 44 What is the transfer of thermal energy through the movement of a gas or a liquid? convection convection Slide 45 Give an example of convection. A pot of boiling water A pot of boiling water Slide 46 What is the transfer of energy by waves that move through matter and space? radiation radiation Slide 47 Give an example of radiation. Radiation from the Sun Radiation from the Sun Slide 48 What doesnt radiation need that conduction and convection need? Matter for heat to travel through Matter for heat to travel through Slide 49 What does conduction require? Two objects must be in contact Two objects must be in contact Slide 50 What does convection require? Requires a gas or a liquid Requires a gas or a liquid Slide 51 What is reflection? Heat or light bounces off an object Heat or light bounces off an object Slide 52 What is anything that slows the movement of thermal energy? insulators insulators Slide 53 What is anything that allows thermal emery to move through it easily called? conductors conductors Slide 54 Why is the handle on a spoon in a glass of hot coffee extremely hot and the foam cup is not very hot at all? Spoon: Metal and good conductor of heat Spoon: Metal and good conductor of heat Foam Cup: Insulator of heat Foam Cup: Insulator of heat Slide 55 What is the best conductor of heat? metal metal Slide 56 Is a solid, liquid, or gas the easiest to transfer energy? solid solid Slide 57 What is the poorest thermal conductor of heat? Gases Gases Slide 58 What is hydroelectric energy? Moving water that can spin to make electricity- Moving water that can spin to make electricity- Hoover Dam Hoover Dam Slide 59 What are fossil fuels and give some examples. Fuels that formed from the remains of once-living things Fuels that formed from the remains of once-living things Coal, oil, and natural gas Coal, oil, and natural gas Slide 60 What are the remains or traces of past life, and it is found in sedimentary rock?
