Name That Unit!
kgms-2
Newton
This accounts for approximately 27% of the matter in the universe.
Dark matter.
F = ma
Isaac Newton.
In "Despicable Me", the villain of this story is introduced through this quote: "'Cause I'm committing crimes with both direction and magnitude!"
Vector.
This phenomenon occurs when light or other waves pass through a narrow opening and spread out.
It’s a key piece of evidence for the wave nature of light and can be observed in both single and double slits.
This effect helps explain patterns observed in experiments like the double-slit experiment.
Diffraction.
kgm2s-2
Joule.
This is the term used to describe a star that has stabilised.
Main-sequence star.
h = E / f
Max Karl Ernst Ludwig Planck.
In "Back to the Future", Doc Brown refers to this type of quantity through this famous quote: "1.21 gigawatts!"
Scalar.
We can know a particle's position.
We can know how fast it is going.
We cannot know both.
Heisenberg Uncertainty Principle.
kgm-1s-2
Pascal.
A type-II supernova leaves this super dense object in it's wake. (DAILY DOUBLE)
Neutron star or blackhole.
ε = -N⋅(ΔΦ/Δt)
Michael Faraday.
In "Interstellar", the robot TARS says "the only way humans have ever figured out of getting somewhere is to leave something behind", as a metaphor for advancement by using this law.
Newton's Third Law.
This concept explains phenomena that can't be fully understood by classical physics alone.
It was key in explaining the unexpected results in the photoelectric effect.
This idea shows how an object's behaviour can change depending on how it's observed.
Wave-particle duality.
kgm2s-3A-2
Ohm.
This type of radiation is crucial evidence supporting the theory of an expanding universe.
Cosmic Microwave Background Radiation (CMBR)
F = Qq / 4πε0r2
Charles-Augustin Coulomb.
In "Man of Steel", Dr. Emil Hamilton says, "The more he's exposed to the Earth's sun, the more powerful he becomes," and hints that this form of energy allows Superman to survive impacts by absorbing it.
Kinetic energy.
This experiment revealed results that couldn't be explained by treating particles as purely solid objects.
It showed that even electrons can create interference patterns typically associated with waves.
Its findings suggest that particles may behave differently when not being observed.
Double-slit experiment.
s4A2kg-1m-2
Farhad.
This law relates the recessional velocity of galaxies to their distance from Earth and provides strong evidence for an expanding universe.
Hubble's Law.
L = 4πr2σT4
(DAILY DOUBLE)
Joseph Stefan and Ludwig Edward Boltzmann.
In "Cars", the following event occurs illustrating this type of collision - one unlikely to happen outside of the Pixar universe: "Lightning McQueen... and Chick Hicks are still neck and neck... and the race continues without much loss of momentum."
Elastic collision.
This experiment involved firing alpha particles at a thin gold foil to investigate atomic structure.
It led to the discovery of the atomic nucleus and the realisation that most of the atom's mass is concentrated in a small, dense region.
The results showed that most particles passed through, but some were deflected at large angles.
Rutherford alpha scattering experiment.
