Mechanics
In physics, this measures an object's resistance to motion. In chemistry, it measures the amount of matter in a substance.
What is mass?
This German physicist formulated the fundamental law linking voltage, current, and resistance.
Who is Georg Ohm?
This process powers the Sun, combining light atomic nuclei into heavier ones and releasing enormous amounts of energy in the process.
What is nuclear fusion?
The Milky Way's nearest neighbor, a barred spiral galaxy.
What is Andromeda?
Near this 2014 movie's black hole, one hour can equal seven years on Earth.
What is Interstellar?
The rate of change of the rate of change of position.
What is electricity?
This device clicks or flashes to detect and measure ionising radiation, making invisible radioactive particles audible and visible.
What is a Geiger counter?
This female scientist is the only person to win a Nobel Prize in both Physics and Chemistry.
Who is Marie Curie?
This animated character's name honors an Apollo astronaut and is the SI unit for luminous flux.
This point on an object behaves as if all of its mass were concentrated there, often simplifying torque and equilibrium problems.
What is center of mass?
This device converts mechanical energy into electricity and forms the basis of wind turbines and hydroelectric dams.
What is an electric generator?
In 1897, this physicist used a cathode ray tube experiment to discover the electron.
Who is J.J. Thomson?
This scientist's thought experiment about a cat in a box was meant to highlight the paradoxes of quantum mechanics.
Who is Erwin Schrödinger?
In Frozen, Elsa's icy powers could be explained with this branch of physics that studies heat transfer and phase changes.
What is thermodynamics?
This force always acts perpendicular to the surface of contact and prevents objects from sinking into surfaces.
What is normal force?
These two famous inventors had a rivalry over the 'war of current' with one championing direct current and the other alternating current.
Who are Thomas Edison & Nikola Tesla?
This ancient Greek philosopher first theorised that matter is made up of indivisible particles he called 'atomos', laying the groundwork for modern atomic theory.
Who is Democritus?
These are the four fundamental forces of nature that govern all interactions in the universe.
What are gravity, electromagnetism, the strong nuclear force, & the weak nuclear force?
In the Star Wars universe, this device allows a ship to travel faster than light speed.
What is hyperdrive?
This unit of measurement, equivalent to about 746 joules per second, is commonly used to express the power of a car.
What is horsepower?
This device transforms electrical energy into a controllable magnetic field, often using a coil of wire and a metal core to lift or move objects.
What is an electromagnet (or solenoid)?
When one atomic nucleus splits and triggers others to do the same, this runaway process unleashes tremendous energy, forming the basis of nuclear bombs.
What is a chain reaction?
This radius marks the boundary around a black hole where not even light can escape.
What is the event horizon?
In this 2001 space epic, a sentient AI and a rotating space station illustrate concepts of artificial intelligence and centrifugal force as a substitute for gravity.
What is 2001: A Space Odyssey?
