Relativity
In special relativity, this quantity is invariant for all observers, regardless of their relative motion.
What is proper time?
This is the unit of electric charge.
What is a Coulomb?
This principle states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted upon by an external force.
What is Newton's First Law of Motion?
This phenomenon occurs where particles act as waves and waves act as particles.
What is wave-particle duality?
This Danish physicist is known for his model of the hydrogen atom and his contributions to understanding atomic structure.
Who is Niels Bohr?
This thought experiment, often used to illustrate the principles of special relativity, involves two observers in relative motion, one inside a moving train and the other outside.
What is the twin paradox?
The generation of an electric current by a changing magnetic field is described by this phenomenon.
What is Electromagnetic Induction
When two objects collide in an isolated system, the total momentum before the collision is equal to this after the collision, provided no external forces act on the system.
What is the conservation of momentum?
It's impossible to know both the position and momentum of a particle with absolute precision simultaneously due to this principle created by a famous german physicist.
What is Heisenberg's Uncertainty Principle?
This Italian physicist is often credited with the invention of the telescope and made significant contributions to the development of modern astronomy.
Who is Galileo Galilei?
In general relativity, this phenomenon occurs when gravity bends the path of light rays.
What is gravitational lensing?
This law states that the magnetic flux through a closed surface is zero.
What is Gauss's law for magnetism?
This law states that for every force applied to an object, there is an equal and opposite force applied by the object.
What is Newton's Third Law of Motion?
This is the name of the process by which an unstable atomic nucleus loses energy by emitting radiation.
What is radioactive decay?
This experiment, conducted by Ernest Rutherford, led to the discovery of the atomic nucleus and provided evidence for the nuclear model of the atom.
What is the Rutherford gold foil experiment?
This is the term for the phenomenon where objects moving at relativistic speeds appear contracted along the direction of motion.
What is Lorentz contraction?
This law describes the relationship between the current flowing through a conductor and the voltage across it, stating that the current is directly proportional to the voltage and inversely proportional to the resistance.
What is Ohm's Law?
This is the third derivative of position with respect to time.
What is jerk?
This principle, named after a German physicist, states that no two electrons in an atom can have the same four quantum numbers.
What is the Pauli Exclusion Principle?
This French physicist is famous for his work on fluid mechanics and hydrodynamics, including his principle regarding pressure in fluids.
Who is Blaise Pascal?
In special relativity, the Lorentz transformation equations describe how measurements of space and time vary between observers in relative motion. This Greek letter is commonly used to represent the Lorentz factor.
What is γ (gamma)?
This law, named after a French mathematician and physicist, states that the magnetic field produced by a current-carrying wire forms concentric circles around the wire.
What is Ampere's Law?
When two objects of unequal mass collide, this phenomenon occurs, where the less massive object experiences a greater change in velocity than the more massive object.
What is impulse?
This principle, named after a French physicist, states that a system can only emit or absorb energy in discrete packets called quanta.
What is Planck's quantum theory?
This French physicist is known for his contributions to the understanding of heat transfer and the development of the metric system.
Who is Joseph Fourier?
