Chemical energy
Heat energy
Fire energy
Wood
What form of stored energy fuels a fire?
Stored energy in the wood
It comes from the heat and light it produces
It comes from the light it gives out
Energy stored in the wood
It comes from the chemical energy it inherently possesses
When you sit in front of a campfire, where does the energy of the fire come from?
Motion and heat
Light and heat
The wood of a fire contains chemical energy that is transformed into what two other energies?
Sound
Light energy
Motion to sound energy
Sound energy
Drummers transform chemical energy into what?
Chemical energy
Energy of fire
Chemical
What type of energy does wood contain?
They contain chemical energy and they both burn
They both give out different forms of energies
They both cause motion
They are made of the same matter
They both have stored chemical energy
They both contain chemical energy
They contain chemical energy
What do wood and gasoline have in common?
The chemical energy gets transformed to sound energy
Vibrating drum head
The drummer strikes the drumhead, using motion to start the drum vibrating. The motion of the vibrating drum head is transferred to sound energy, which is what you hear
The motion of the vibrating drum causes the sound we hear
How is the sound of a vibrating drum produced by energy?
Chemical energy
Light and heat energy
Light and heat
Heat
Wood is transformed into which type of energy?
The drummer cause the drum to vibrate which causes the sound we hear
Vibrating drum head
Moving drumstick hits drum head causing vibration which is what is heard
He changes the chemical energy to sound
How does a drummer transfer motion energy to sound energy?
Chemical energy
Heat energy
Gasoline as a fuel
What type of energy do cars use to move?
Sound
Light and heat
Chemical energy is changed into light and heat
What is the stored energy in wood be turned into when burned in a campfire?
The chemical energy in wood burned in a campfire is converted to light and heat whereas in a car, the chemical energy in gasoline is converted to motion and heat
The former produces chemical energy whereas the latter causes motion
Burning wood produces light and heat whereas burning gasoline produces motion and heat
How is burning wood in a campfire different from burning gasoline in a car?
Sound
Motion
Light
The motion of a vibrating drum head creates what?
Energy often changes from one form to another. For example, the drummer transfers motion to sound energy. When the moving drumstick strikes the drum head, the drum starts to vibrate. The motion of the vibrating drum head creates the sound you hear. Any form of energy can change into any other form. Frequently, one form of energy changes into two or more different forms. Have you ever sat in front of a campfire? What are two things you notice? The fire creates light. It is also warm by the fire, meaning it creates heat. The energy of the fire comes from the stored energy in the wood. The wood contains chemical energy. As it burns, the chemical energy is changed into light and heat. Not all chemical energy changes produce light and heat. Our cars use gasoline as a fuel. Gasoline contains chemical energy. When our cars burn gasoline in their engines, it is converted into motion and heat. When energy changes forms, energy is conserved.
