What type of collision conserves both momentum and kinetic energy?
Elastic
What kind of matter is theorized to hold a wormhole open?
Exotic matter with negative energy.
What transfers heat fastest: metal or wood?
Metal
If you lived on a neutron star, how would time change for you?
It would slow down dramatically due to gravity.
This physicist's namesake experiment demonstrated that observing quantum particles changes their behavior
Young
Why does a fast-spinning wheel resist changes in orientation?
Gyroscopic effect
What hypothetical energy repels gravity in the universe?
Dark energy
Why is it impossible to reach absolute zero?
Infinite energy removal would be required.
Could a black hole ever shrink instead of grow?
Yes—via Hawking radiation.
Which physicist’s famous inequality challenged the idea of hidden variables in quantum mechanics?
Bell
Can an object have zero velocity but still be accelerating?
Yes—at the peak of a projectile’s motion.
If a spaceship moves close to light speed, how does its length appear to an outside observer?
It contracts
In a chaotic system, why is prediction so difficult?
Small changes in initial conditions grow exponentially (butterfly effect).
If you could travel faster than light, what strange effect would you notice?
You could see events happen before their cause.
Which principle suggests that all quantum states exist until observed?
Superposition
A projectile explodes mid-air. What quantity remains conserved?
Momentum
What kind of hypothetical engine could extract energy from a rotating black hole?
Penrose process
If you put your hand in an oven at 200°C and another in boiling water at 100°C, which burns faster?
The water
What happens if you travel near the speed of light for a year?
You age less than people on Earth (time dilation).
Which paradox suggests measuring a quantum system affects its outcome?
Observer effect
What theorem states that the time-averaged kinetic energy equals half the time-averaged potential energy in a bound system?
Virial theorem
What quantum field phenomenon suggests that empty space is never truly empty, constantly generating virtual particles?
Vacuum fluctuations
What state of matter exists at ultra-high temperatures?
Quark-gluon plasma
What hypothetical particle travels faster than light?
Tachyon
Which interpretation of quantum mechanics suggests particles take every possible path?
Feynman's path integral
