Forms of Energy
What is the form of energy from heat?
Thermal
What are the two types of energy sources?
Renewable and Nonrenewable
What is the difference between an open and closed circuit?
Open circuit: If it is open, it is broken! No electricity flows causing no light or output
Closing Circuit: If it is closed, it flows! Energy flows causing a light or output!
What caused static electricity?
The transfer of negative charge (electrons)
What materials can be used to make an electromagnet?
battery, wire, rubber band, nail
What is another name for light or solar energy?
Radiant
A. Energy can be created to do work.
B. Energy can be transformed.
C. Energy can be transferred or moved from place to place
D. Gravity.
C. Energy can be transferred or moved from place to place
What can electrical energy produce or cause?
Mechanical (motion)
Thermal (heat)
Radiant (light)
Sound
What causes static electricity?
Friction (rubbing material or object)
What is something can make the electromagnet stronger?
Add more coils around the nail
Add a larger battery
What is the energy that is from motion?
Mechanical
Less energy in the circuit. The energy was transformed into radiant and thermal energy.
What are the main parts of a circuit?
What are the possible outcomes of static electricity? Name at least 2.
Objects attract or repel from another
Static Shock (discharge)
Static Cling
How do you know if the electromagnet you made works?
There will be a magnetic field that attracts magnetic items.
What is the acronym we use for the forms of energy?
M.E.L.T.S
What is the energy transformation for a fan?
electrical to mechanical
What is the difference between conductors and insulators?
Give an example of each!
Conductors allow electricity to flow through. (paper clip, iron nail, metal zipper, wire)
Insulators do not allow electricity to flow through. (plastic, rubber eraser, wooden toothpick, string)
What are 4 objects that be used during a static electricity lab?
balloon, felt, carpet, sweater/clothing, hair, paper, plastic comb, slide.
If your electromagnet does not work, what are 3 things you should check?
Battery had energy
Conductors are touching conductor and power source
nail is metal
wire is copper (or a conductor)
wire is touching the power source on positive and negative end.
What are the main forms of energy?
Mechanical, Electrical, Light, Thermal, Sound
Name 2 renewable and 2 nonrenewable energy sources.
Solar, hydropower, wind
natural gas, coal, fossil fuels
What is electrical energy?
The flow of electrical charge.
When you go down a slide, why does your hair stand up?
What types of energy are being used in an electromagnet?
electrical, magnetic, mechanical (lifting metal), and thermal (heat from energy flowing).
