Energy Basics
This law states that energy cannot be created or destroyed, only changed in form.
What is the Law of Conservation of Energy?
When a match is lit, chemical energy changes into these two forms of energy.
What are heat energy and light energy?
Electricity is the flow of these negatively charged particles.
What are electrons?
In this type of circuit, electrons flow in only one path.
What is a series circuit?
According to Ohm’s Law, voltage equals current multiplied by this quantity.
What is resistance?
This type of energy is produced when electrons move.
What is electrical energy?
Rubbing your hands together changes mechanical energy into this type of energy.
What is thermal (heat) energy?
According to the law of charges, these types of charges attract.
What are opposite charges?
n this type of circuit, one bulb going out does not affect the others.
What is a parallel circuit?
If voltage is 36 volts and current is 4 amps, this is the resistance.
What is 9 ohms?
This type of energy is produced by vibrating matter.
What is sound energy?
A battery powering a radio changes chemical energy into this form of energy.
What is sound energy?
This type of electricity involves the buildup of electric charges.
What is static electricity?
Electricity cannot flow if a circuit is in this condition.
What is open (or broken)?
If current is 15 amps and resistance is 2 ohms, this is the voltage.
What is 30 volts?
The total amount of kinetic energy in an object.
What is thermal energy?
Energy changes from one form to another during this process.
What is an energy transformation?
This occurs when charges transfer by touching objects together.
What is conduction?
his type of current changes direction repeatedly.
What is AC current?
If the resistance in a circuit increases while voltage stays the same, this happens to the current.
What is the current decreases?
The sum of potential and kinetic energy in an object.
What is mechanical energy?
This type of energy is produced when atomic bonds are formed or broken.
What is chemical energy?
Lightning is an example of this type of charge transfer without touching.
What is induction?
Batteries produce this type of current.
What is DC current?
If a circuit has a voltage of 24 volts and a resistance of 6 ohms, this is the current.
What is 4 amps?
