Question 1: What principle explains why passengers lurch forward when a car brakes suddenly?
Buoyancy difference
Inertia (Newton's first law)
Conservation of energy
Third law reaction forces
Question 2: Which quantity is conserved in an isolated closed system when objects collide elastically?
Both momentum and kinetic energy
Only momentum
Neither momentum nor energy
Only kinetic energy
Question 3: How does doubling the frequency of a light wave affect its energy per photon?
Energy increases by factor four
Energy remains unchanged
Energy per photon doubles
Energy per photon halves
Question 4: A satellite in circular orbit suddenly fires its engine briefly to speed up. What happens to the orbit immediately after the burn?
It becomes an elliptical orbit with perigee at burn point
It escapes immediately on a hyperbolic path
It falls straight toward the Earth
It stays circular but at higher altitude
Question 5: Why does adding more resistors in parallel to a circuit typically increase the total current drawn from the source?
Parallel branches provide additional current paths, reducing total resistance
Voltage across each resistor drops dramatically
Current always stays the same regardless of wiring
Each resistor steals energy from others
Question 6: Which statement best corrects the myth that heavier objects fall faster than lighter ones in vacuum?
Only shape determines fall speed even in vacuum
Lighter objects float upward due to buoyancy even in vacuum
Heavier objects accelerate faster because gravity pulls more
In vacuum, all objects accelerate equally under gravity regardless of mass
Question 7: Which experimental observation most strongly supports the particle nature of light?
Photoelectric effect where photons eject electrons with energy dependent on frequency
Continuous spectrum from a blackbody
Refraction of light through glass
Interference fringes in a double-slit experiment
Question 8: When analyzing a physical problem, which habit most improves model reliability?
Stating assumptions and checking their domain of validity
Relying solely on intuition without math
Avoiding any approximations ever
Making models as complex as possible immediately
