Advanced Mechanics
This quantity is calculated as mass multiplied by velocity and is conserved in isolated systems.
What is momentum?
This type of charge produces a magnetic field when it moves through a conductor.
What is an electric charge?
This phenomenon demonstrates that light can travel through a vacuum and does not require a medium.
What is electromagnetic wave propagation?
This theory proposes that the universe began from a singularity and has been expanding ever since.
What is the Big Bang theory?
This type of motion occurs when an object moves under the influence of gravity alone, with no other forces acting.
What is free fall?
This force acts perpendicular to the velocity of an object in circular motion and points toward the center of the circle.
What is centripetal force?
This rule is used to determine the direction of the force on a current-carrying conductor in a magnetic field.
What is the right-hand palm rule?
This experiment showed that light behaves as a wave, producing an interference pattern when passed through two slits.
What is the double-slit experiment?
This type of spectrum is produced when light passes through a cool gas, leaving dark lines at specific wavelengths.
What is an absorption spectrum?
This device converts electrical energy into mechanical energy using the motor effect.
What is an electric motor?
This is the shape of the trajectory of a projectile under uniform gravitational acceleration, assuming no air resistance.
What is a parabola?
This law states that the induced electromotive force in a circuit is proportional to the rate of change of magnetic flux.
What is Faraday’s Law of Electromagnetic Induction?
This effect provided evidence that light can behave as a particle, ejecting electrons from a metal surface.
What is the photoelectric effect?
This scientist proposed a model where electrons orbit the nucleus in quantised energy levels.
Who is Niels Bohr?
This phenomenon occurs when light bends as it passes from one medium to another due to a change in speed.
What is refraction?
This principle explains why a figure skater spins faster when pulling in their arms.
What is conservation of angular momentum?
This law explains why the direction of an induced current opposes the change that produced it.
What is Lenz’s Law?
This equation relates the energy of a photon to its frequency: E=hf.
What is Planck’s equation?
This process occurs when a heavy nucleus splits into smaller nuclei, releasing energy and neutrons.
What is nuclear fission?
This discovery by Rutherford involved firing alpha particles at gold foil and led to the conclusion that atoms have a small, dense, positively charged nucleus.
What is the Gieger-Marsden gold leaf experiment?
This expression calculates the work done to bring a mass from infinity to a distance r from a massive body.
What is U=-GMm/r?
This rotating device operates without electrical connections to the rotor, using a changing magnetic field in the stator to induce current and produce torque.
What is an AC induction motor?
This postulate of Einstein’s theory of special relativity states that the speed of light in a vacuum is constant for all observers, regardless of their motion.
What is the constancy of the speed of light?
This fundamental interaction is responsible for holding quarks together inside protons and neutrons.
What is the strong nuclear force?
This phenomenon occurs in conductive materials exposed to a changing magnetic field, generating circulating currents that oppose the change and can cause heating.
What are eddy currents?
