what is energy?
|
the ability to do work or make things happen
|
the ability to....
|
|
|
what is matter?
|
anything that has mass and takes up space
|
anything that...
|
|
|
what does it mean when something INTERACTS with something else
|
to work with, to work together with
|
Example: Energy and matter interact.
|
|
|
what is an energy source?
|
the energy or “fuel” that allows an object to function
|
|
|
|
what is "energy released"?
|
energy that comes from an object after it gets energy from the energy source
|
Example for 4 & 5: A light bulb uses electrical energy (energy source) to release light and heat (energy released).
|
|
|
what are forms of energy?
|
ways or forms in which energy can exist
|
Example: The 5 forms we have studied are: chemical, electrical, light, heat, motion.
|
|
|
what is an electrical circuit?
|
a closed path that provides a way for electrical energy to travel
|
|
|
|
List the 5 forms of energy we have been discussing in class.
|
chemical, electrical, light, heat, energy of motion (4 types of motion - sound, water, wind, physical/mechanical)
|
|
|
|
give an example of sound motion
|
Horn, radio, speech
|
|
|
|
give an example of water motion
|
Ripples in water, waves in water; a water wheel using flowing water
|
|
|
|
give an example of wind motion
|
Hurricane, tornado, windmill, fan
|
|
|
|
give an example of physical/mechanical motion
|
Person, any animal (for physical); robot, car, any machine with moving parts (for mechanical)
|
|
|
|
Describe the path the electrical current takes. How does the energy travel?
|
The electrical current travels in a circular path. It goes from one of the battery terminals, through the first wire, into the light bulb, out the second wire, and to the second battery terminal.
|
|
|
|
c. What needs to happen in order for the light bulb to light? How does the battery give the light bulb what it needs to light?
|
In order for the electrical energy to flow, there needs to be a closed circuit (complete, unbroken path) from the first battery terminal to the second battery terminal. The electrical energy passes through the light bulb and releases light and heat energy.

|
|
|
How are matter and energy related?
|
Matter and energy interact with each other.
|
|
|
|
Is energy a type of matter?
|
Energy is a fuel that allows matter to do work.
|
|
|
|
Is matter a type of energy. Please explain.
|
Matter and energy interact with each other. Energy is a fuel that allows matter to do work. Energy is not a type of matter and matter is not a type of energy.
|
|
|
|
Explain Conservation of Energy
|
Energy is neither created nor destroyed. Energy does not appear out of nothing and it does not disappear into nothing. Energy simply changes form.
