Bonus round! Name as many (fairly prevalent) physicists as possible within 45 seconds.
Another team can challenge your answers and name more in 45 seconds without repeating the physicists you mentioned.
What sport does Nathan perform?
Swimming
What is the period for a pendulum under the very small angle assumption?
T=2(pi)sqrt[l/g]
Bonus round! Send one member of your team up to solve a tricky question. The question will be revealed in an instant and you will need to write the answer on the board. The crowd will learn the question 60 seconds after you start and will race you to get the answer first.
Let there be a massless bar of infinite length. Weights are attached every length L and increase as m, 2m, 3m, 4m, 5m, and so on. Determine whether the bar can move or not, if initially at rest.
What is a capacitor or an inductor?
A capacitor stores charge and an inductor creates a magnetic field (or similar answers are correct).
What common mirror makes images bigger at a distance closer than the focal length?
Concave
What embarrassing thing did Gary put in a Kahoot during one of the first Physics Association meetings?
An atom loses a proton to become negatively charged
Describe what a fictitious force is.
A force that only emerges because of the reference frame being considered
What is the difference between the decay constant and the half life for a radioactive substance?
The decay constant is the exponent coefficient for the base 1/e, while the half life divides the time in the exponent for the base 1/2.
What is Kirchoff's voltage law for circuits?
Voltage across parallel lines is equal
What is the formula for the energy of a light wave and the value of the constant attached to the formula?
E = hf, h=6.63x10^-34 Joule-seconds
What is Blake's favourite classical composer? (can name any of the top 3)
Mahler, Shostakovich, Tchaikovsky
Why is the Moon receding from the Earth?
Angular momentum is being transferred from the tides caused by the Moon on Earth to the moon, meaning that it travels faster and thus requires a larger radius of orbit.

Electron, Tau particle, Muon (neutrino versions is optional)
Almost the same
What is the most common technique used in optics?
Ray tracing
