Circuits
Doesn't allow current to flow
What is an open circuit?
A disturbance that travels through space and matter, transfers energy from one place to another
What is a wave?
A material or object that produces a magnetic field
What is a magnet?
The total energy of an isolated system remains constant
What is the conservation of energy?
Deals with heat, work, and temperature, and their relation to energy, radiation, and physical properties of matter
What is thermodynamics?
Allows current to flow
What is a closed circuit?
A wave that travels through a medium. Ex. longitudinal waves and transverse waves
What is a mechanical wave?
North and South
What are the 2 poles on a magnet?
KEi+PEi=KEf+PEf
What is the equation?
"In all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy.
What is the 2nd law of thermodynamics?
A source of power
What is a battery?
Created as a result of vibrations between an electric field and a magnetic field
What is a electromagnetic wave?
Iron, steel, nickel, cobalt
What do magnets attract?
In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy.
What is an example of conservation of energy?
Nicolas Léonard Sadi Carnot
Who is the father of thermodynamics?
Only has one path that current can flow through
What is a series circuit?
Radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What waves are apart electromagnetic spectrum?
Heating or Hammering
What demagnetize a magnet?
Energy can neither be created nor destroyed
What does the law of conservation of energy state?
Moving an airplane, generating electricity, or even riding a bicycle
How is thermodynamics used today?
Contains a parallel circuit and a series circuit
What is a complex circuit?
Amplitude, wavelength, frequency, period, and velocity
What are the properties of a wave?
Earth
What is the biggest magnet?
Transform energy from one form to another
How do we use energy?
measure of the molecular disorder, or randomness, of a system
What is entropy?
