EVALUATION 2026 QUESTION BANK
COMPLETE STUDT GUIDE 2026 UPDATE
Theory - ANSWER-a well-substantiated explanation of some aspect of the natural world
hypothesis - ANSWER-a proposed scientific explanation for a set of observations
Johannes Kepler - ANSWER-German astronomer who first stated laws of planetary
motion (1571-1630)
Ptolemy - ANSWER-Alexandrian astronomer who proposed a geocentric system of
astronomy that was undisputed until Copernicus (2nd century AD)
Polaris - ANSWER-the north star
Copernicus - ANSWER-Polish astronomer who produced a workable model of the solar
system with the sun in the center (1473-1543)
gram - ANSWER-a metric unit of mass equal to one thousandth of a kilogram
meter - ANSWER-the basic unit of length adopted under the Systeme International
d'Unites (approximately 1.094 yards)
scientific method - ANSWER-a series of steps followed to solve problems including
collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions
Newton's Law of Gravity - ANSWER-Law stating any two objects are attracted to each
other; the magnitude of the attraction depends on the masses of the two objects and the
distance between the two objects.
Gravity is slightly less on a mountain and therefore you weigh less - w = m x g -
ANSWER-Why is your weight less on a mountain top compared to sea level?
Scalar quantity - ANSWER-A quantity that has only magnitude
Vector quantity - ANSWER-quantity having both magnitude and direction
Speed/velocity - ANSWER-rate at which an object covers distance
Acceleration of gravity - ANSWER-9.8 m/s2
, acceleration - ANSWER-(physics) a rate of change of velocity
Newton's First Law of Motion - ANSWER-Law: "An object at rest will remain at rest, and
an object moving at a constant velocity will continue moving at a constant velocity,
unless it is acted upon by an unbalanced force." Another name is Law of Inertia
Newton's Second Law of Motion - ANSWER-Law: The acceleration of an object
depends on the mass of the object and the amount of force applied.
Newton's Third Law of Motion - ANSWER-Law: Whenever one object exerts a force on
a second object, the second object exerts an equal and opposite force on the first.
Inertia - ANSWER-(physics) the tendency of a body to maintain is state of rest or
uniform motion unless acted upon by an external force
Centripetal force - ANSWER-the inward force on a body moving in a curved path
around another body
Watt - ANSWER-a unit of power equal to 1 joule per second; after James ____ who
found a way to relate the the new unit to Horsepower in the invention of the steam
engine.
Joule - ANSWER-SI unit of energy
Law of the Conservation of Energy - ANSWER-energy may change from on form to
another, but the total amount of energy does not change - energy cannot be created or
destroyed
Power - ANSWER-(physics) the rate of doing work
Work - ANSWER-Measure of change that a force causes when it acts upon something
Kinetic Energy - ANSWER-Energy of motion
Potential Energy - ANSWER-the mechanical energy that a body has by virtue of its
position
Rest Energy - ANSWER-the energy equivalent to the mass of a particle at rest in an
inertial frame of reference
General Theory of Relativity - ANSWER-A theory: a description of spacetime formulated
by Einstein explaining how gravity affects the geometry of space and the flow of time;
gravity is a warping of space-time.
energy - ANSWER-Mass in congealed _____.
