Energy
The energy associated with motion.
What is kinetic energy?
Metals like gold, copper, iron.
What is a conductor?
Circuit elements are all connected in a single loop.
What is a series circuit?
The parts of a magnet where magnetic field is strongest.
What are magnetic poles?
These types of magnetic poles repel each other.
What are like poles?
The energy gained by gaining altitude.
What is gravitational potential energy?
An excess of electrons in an object.
What is a negative charge?
Voltage is the same across every branch.
What is a parallel circuit?
These three are the only ferromagnetic elements.
What are iron, cobalt, and nickel?
Newton-meters, or joules.
What is the SI unit for work?
The attractive or repulsive force between two charges.
What is electrostatic force or Coulomb force?
The product of the current and resistance equals the voltage.
What is Ohm's law?
These particles are what cause magnetism.
What are electrons?
What is from high potential to low potential.
The combination of kinetic energy and potential energy.
What is mechanical energy?
The area around a charged object in which electric force can act.
What is electric field?
When one light bulb shines brighter than the other in a circuit, it has more of this.
What is power output?
When these align, a substance becomes magnetic.
What are magnetic domains?
When there is no resistance in a loop, the circuit overloads.
What is a short circuit?
The total energy at the beginning is equal to the total energy at the end. Energy is not created or destroyed.
What is the law of conservation of energy?
This force is similar to electric force, but it only attracts, while electric force either attracts or repels.
What is gravitational force?
Circuit elements connected in series have the same amount of this.
What is current?
This type of magnet can be turned on and off.
What is an electromagnet?
Twisting a current-carrying wire into this shape gives a steady magnetic field.
What is a solenoid?
