Exam proficiency Questions and Must have
marking scheme Updated version 2024/2025
Potential energy - correct answer Energy that is stored
Formula for work - correct answer work = force x displacement
Gravitational potential energy - correct answer Energy an object has due to its height
above the ground. Increases with mass and height.
Chemical potential energy - correct answer Energy that is stored in the chemical bonds
in a substance
Elastic potential energy - correct answer Energy stored in stretched springs, rubber
bands, etc.
Electromagnetic energy - correct answer Energy carried by electromagnetic waves.
Light energy.
Thermal energy - correct answer Energy from the motion of atoms and molecules.
Depends on mass and temperature
Law of conservation of energy - correct answer Term for the fact that energy cannot be
created/destroyed, only transferred/converted
Oscillation - correct answer A repetitive motion that occurs around a center point or
equilibrium
Equilibrium - correct answer A position or state to which an oscillating object eventually
returns to
,Wave - correct answer A repeating and periodic disturbance (oscillation) that travels
from one point to another, transferring energy
Mechanical waves - correct answer Type of waves that require a medium (air, water,
etc.) To travel through, cannot travel through a vaccuum
Transverse wave - correct answer Wave where the oscillation is perpendicular to the
direction the wave is traveling
Longitudinal wave - correct answer Wave where the oscillation occurs along the
direction the wave is traveling
Electromagnetic waves - correct answer Waves with both an electric and magnetic
component. Can only be transverse waves and can travel through a vaccuum
Compression - correct answer Region of longitudinal wave where particles are close
together
Expansion - correct answer Region of longitudinal wave where particles are far apart
(aka rarefaction)
Crest - correct answer The highest point in a wave above equilibrium
Trough - correct answer The lowest point in a wave under equilibrium
Amplitude - correct answer The distance between a wave's equilibrium and
crest/trough in a transverse wave, or how compressed/expanded the medium becomes
in a longitudinal wave
Wavelength - correct answer The horizontal distance after which the wave repeats
, Period - correct answer The amount of time needed for one full oscillation/one wave to
pass
Frequency - correct answer Number of wave oscillations in a given period of time
Sound wave - correct answer A disturbance we can hear that moves through a
medium away from the source
Matter - correct answer Anything that takes up space and has mass
Atom - correct answer The basic building block of matter
Valence electrons - correct answer The electrons in the outer most shell of an atom
Element - correct answer A pure substance made of only one kind of atom, defined by
its proton count
Atomic number - correct answer The number of protons in the nucleus of an atom
Chemical - correct answer Any substance that has a definite, fixed composition
Compound - correct answer a chemical combination of two or more different elements
in a fixed ratio
Chemical bonds - correct answer the attractive forces that hold atoms together
Organic compound - correct answer Compounds that contain carbon and hydrogen
Inorganic compounds - correct answer Compounds that are not organic compounds
