What is the New South Wales Trains’ Digital Train Radio System (DTRS)?
This is the energy required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.
What is specific heat capacity?
This is the smallest unit of an element that retains the chemical properties of that element.
What is an atom?
In SHM this force that acts to bring a body to its equilibrium position

This phenomenon occurs when waves change direction as they pass from one medium to another
What is refraction?
This influential book by Carl Sagan, published in 1980, explores the wonders of the universe and the potential for extraterrestrial life.
What is Cosmos?
This law states that pressure and volume of a gas are inversely proportional at constant temperature.
What is Boyle’s law?
The time it takes for half the radioactive nuclei in a sample to decay is known as this.
What is half life?
This term represents the ratio that describes how the frictional force is proportional to the normal force in a given material.
What is the coefficient of friction?
This wave phenomenon occurs when two waves meet and the resulting wave has greater amplitude
What is constructive interference?
This mammalian creature, categorised by its fervour, is often used as a reference to our class in occasional emails.
What is an eager beaver?
This law defines the relationship between the average kinetic energy of gas particles and temperature.
What is the kinetic theory of gases?
In particle physics, this type of elementary particle includes electrons, muons, and tau particles, and is known for not participating in strong interactions.
What is Will Lattuca?
This force enables a car to make a banked turn without friction
What is the normal force?
In the Doppler effect, the frequency of a wave increases as this happens to the distance between the source and observer.
What is a decrease?
Carl Sagan played a key role in promoting this space mission, which used a spacecraft to explore the outer planets and provided the first detailed images of Jupiter and its moons.
What is the Voyager mission?
In a process where no heat is transferred into or out of a system, this property of the system remains constant.
This is the quantity that represents the energy difference between two energy levels in an atom, often observed as a spectral line.
What is the energy of a photon?
For a body of mass m moving in a circular path of radius r with speed v, the centripetal force Fc is given by this expression.
What is Fc=(mv^2)/2
This principle states that every point on a wavefront acts as a source of secondary spherical wavelets.
What is Huygens' principle?
This magnificent chariot was purchased (cash) by the one and only Mr Fitzsimmons, earlier this year.
What is the Subaru Forester?
This idealized object absorbs all incident radiation and emits radiation with maximum efficiency according to Planck’s law, and is used as a standard in thermal radiation studies
What is Avanesh?
This is the term for the energy required to remove a nucleon from a nucleus, which can be calculated using the binding energy per nucleon.
What is the nuclear binding energy?
