Energy Transfer and types
What is energy transfer
What is to move energy from one place to another or from one object to another
a deer running across the road has what kind of energy
kinetic
no
What is a system?
a set of interacting parts that make up a complex whole
What is the definition of energy?
what is
the ability to make things move or change
Mark has a flashlight that does not need new batteries and never needs a charge.
Instead, it has a hand crank that makes the light shine.
What is the energy source for this flashlight?
a. it does not have an energy source
b. the generator converting kinetic energy to electrical energy
c. the hand crank's kinetic energy
d. Mark's kinetic energy from his hand moving the crank
d. Mark's kinetic energy from his hand moving the crank
what kind of energy do you feel as heat
thermal
solar panels and hydropower dams are examples of what kind of energy
renewable
what type of energy does a battery have
potential
what is a claim?
your answer to the question
What is the energy that an object has when it is moving?
what is kinetic energy
What kind of energy is stored in the bonds between atoms?
chemical
does a solar panel create its own energy?
no
What is the difference between transferring energy and converting it?
transfer - place to place, object to object
convert- one type of energy to another
what is the Law of Conservation of Energy say?
energy can't be created or destroyed, but it can be converted or transferred
a kid kicked a soccer ball
Describe how the energy transferred through this system
what is
from the kid's leg to the ball
potential (technically chemical potential)
What is the difference between renewable and nonrenewable energy?
renewable = naturally replenising
nonrenewable = finite, takes millions of years to make more
what is evidence
information that supports or refutes your claim
what is chemical energy?
energy stored in the bonds between atoms
Mila ate a banana as an afternoon snack, then decided to go on a jog. She connected her headphones to listen to music as she ran.
A little while into her jog, her music stopped playing.
She had a power bank with her, so she plugged her phone in to charge.
The music started to play again.
Why did Mila's music start playing again once she plugged her phone into the charger?
A. Energy transferred from her phone to the charger
B. Energy transferred from her charger to her phone
C. Her phone created energy to hold a charge
D. Her charger created energy to charge her phone
E. Energy converted from her charger to her phone
What is
B. Energy transferred from her charger to her phone
describe the types of energy associated with a generator
converts kinetic to electrical
Does energy ever just disappear?
no
energy cannot be created or destroyed locoe
What is reasoning
AND why is it important
explaining why your evidence matters
makes an argument stronger, makes you sound like you know what your talking about
what are 3 examples of electromagnetic energy?
varies but the answer on the test says
microwave
light
xrays
