Energy Transfer
Give an example of energy transfer
??
When does a collision happen?
What kind of energy is stored in a battery?
Chemical Energy
Energy
the ability do work/ make things happen
What is Kinetic Energy?
Energy of something that is in motion
Can energy be created?
No. Energy cannot be created nor destroyed.
Give 2 examples of a collision
- Puppy licking your face
- Wrecking ball hitting a building
- Bowling
What is Electrical Energy?
Energy that comes from an electric charge
What is the measurement of how high or low something is?
Pitch
What is potential energy? Give an example as well
Energy that is stored in an object. Rock at the top of a hill before it rolls down
What are 3 ways energy can be transferred?
Light, sound, heat, electrical currents, etc
True or false: The lighter the object, the more energy that object carries.
False. The heavier an object, the more energy it carries
How does sound energy transfer?
Through sound waves
Thermal Energy
Caused when molecules rub against each other, causing friction
Where does most of the worlds energy come from?
The Sun
Why do circuits need to maintain a closed loop?
Electricity only flows through a "closed circuit." If there was an opening the flow of electricity would be stopped
What affects the amount of energy transferred during a collision?
The weight and speed of the moving object
Give an example of the following:
- Something that transfers electric energy into heat
- Something that transfers electric energy to sound
- Toaster
- Boom box/ radio
Wavelength
What is the distance from one point of a wave to the same point on another wave called?
Where do we get our energy from?
How can very loud music break glass that is near by?
Energy is converted to motion energy that causes the glass to bend, move and eventually shatter.
The energy of motion from the swinging drum stick is transferred to the gong, which then vibrates producing sound.
What states of matter carry heat through convection?
Liquid & gas
Energy Conversion / Transformation
Process of changing energy of one form, into another
Explain what fossil fuels are made of and give an example of one.
Fossil Fuels are made from the remains of plants and animals that lived long ago. The sun gave these things energy to grow.
Ex: Coal, natural gas, oil
