G, E & B Fields
This type of field exists around any object that has mass
What is a Gravitational Field?
This scientist is credited with the Three Laws of Motion and the Law of Universal Gravitation
Who is Isaac Newton?
In this fundamental formula, the variable 'm' represents mass, while 'a' represents acceleration, with their product equaling force
What is F=ma?
Name the phenomenon where a current-carrying wire experiences a force in a magnetic field
The motor effect.
An object moving at constant speed must have a net force acting on it.
Constant speed in a straight line means zero net force
This type of field is created between two parallel plates connected to a DC power supply
What is a uniform electric field?

Who are Albert Einstein and Nikola Tesla?
This formula requires a value for acceleration, time and initial velocity
What is v=u+at?
Name the effect where a conductor moving through a magnetic field has a voltage induced across it
Electromagnetic induction.
Magnetic fields push stationary charges
magnetic force requires motion
The trajectory of a charged particle entering a uniform magnetic field at a 90 deg angle
What is a circular path?
His 1860s equations showed that an oscillating electric field produces a perpendicular magnetic field, predicting the existence of electromagnetic waves
James Clerk Maxwell
This letter represents the constant of proportionality in universal gravitation
What is G?
According to Einstein, it's the relativistic effect where an object moving at high speed appears shorter in the direction of motion to a stationary observer
What is length contraction? (or What is Lorentz contraction?)
Doubling the voltage always doubles the current
only true if resistance stays constant (Ohm’s law)
This value represents the work done per unit charge in moving a charge between two points in an electric field
What is potential difference (or Voltage)?
He discovered electromagnetic induction and visualized magnetic fields as "lines of force," despite having no formal mathematical training
Who is Michael Faraday?
Newton’s second law can be stated more fundamentally as the derivative of this vector quantity with respect to time (t)
What is momentum (p)?
Name the effect that explains why GPS satellites need relativistic time corrections
Time dilation
If a charged particle moves faster in a magnetic field, the magnetic force decreases because it spends less time in the field
magnetic force increases with speed, F=qvB
This law states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them
What is Coulomb's Law?
Mr Tabone's Profile Picture (Hint: Cat)
Who is Erwin Schrödinger?
This is the SI unit for the specific heat capacity (c)
What is Joules per kilogram-Kelvin (J/(Kg*K))?
Name the phenomenon that causes electrons to be emitted from a metal surface when light shines on it
The photoelectric effect.
A proton and electron in the same electric field experience the same acceleration because they have equal and opposite charge
Force is equal in magnitude, but acceleration differs because electron mass is far smaller, so it accelerates much more
