🟦 ENERGY BASICS
The energy an object has because it is moving.
What is kinetic energy?
The flow of electric charge.
What is current?
Energy transferred due to temperature difference.
What is heat?
A closed loop that allows current to flow.
What is a circuit?
The rate at which energy is transferred.
What is power?
The energy stored due to an object’s position in a gravitational field.
What is gravitational potential energy?
The unit used to measure current (coulombs per second).
What is an ampere (amp)?
Heat always moves from ___ temperature objects to ___ temperature objects.
What is high to low?
A device that keeps charges separated to maintain voltage.
What is a battery?
The unit of power equal to one joule per second.
What is a watt?
The unit used to measure all forms of energy.
What are joules?
The difference in electric potential between two points.
What is voltage?
Temperature is related to the average ______ of particles.
What is kinetic energy?
In this type of circuit, current has only one path.
What is a series circuit?
A device that stores electrical energy temporarily.
What is a capacitor?
Energy changes forms but is never created or destroyed—this law is called what?
What is the conservation of energy?
The particles that actually move in a wire.
What are electrons?
The lowest possible temperature that cannot actually be reached.
What is absolute zero?
In this type of circuit, current splits into multiple paths.
What is a parallel circuit?
Total resistance formula for resistors in series.
What is Rₜ = R₁ + R₂ + ...?
In a pendulum, energy shifts continuously between these two types.
What are kinetic and potential energy?
The equation relating current, voltage, and resistance.
What is Ohm’s Law (I = V/R)?
The law stating that energy is conserved in a system.
What is the first law of thermodynamics?
Adding resistors in parallel does what to total resistance?
What is: it decreases?
Materials that have zero resistance at very low temperatures.
What are superconductors?
