C165 OA EXAM QUESTIONS WITH
VERIFIED ANSWERS
/. Physics - Answer-The study of forces and energy
/.Chemistry - Answer-The study of atoms and molecules, their structures, and their
interactions to form substances
/.Earth Science - Answer-The study of Earth and other planet, including their physical
structure, materials, and processes
/.principle of falsification - Answer-Principle that only falsifiable statements can be
subject to scientific inquiry
/.Theory - Answer-a statement that explains a wide range of observations and is
supported by a large body of scientific evidence. Explains how and why things happen
/.Length - Answer-meter (m)
/.Mass - Answer-kilogram (kg)
/.time - Answer-second (s)
/.temperature - Answer-Kelvin (K)
/.mega - Answer-M 10^6
/.kilo - Answer-k 10^3
/.deci - Answer-d 10^-1
/.centi - Answer-c 10^-2
/.milli - Answer-m 10^-3
/.micro - Answer-10^-6
/.nano - Answer-n 10^-9
/.speed - Answer-meter per second, m/s
divide distance traveled by amount of time it took to travel that distance
/.area - Answer-square meter (m^2)
, /.volume - Answer-cubic meter (m^3)
/.density - Answer-kilograms per cubic meter (kg/m^3) mass divided by volume
/.direct relationship - Answer-a relationship in which one variable increases with an
increase in another variable
/.inverse relationship - Answer-a relationship in which one variable decreases when
another variable increases
/.velocity - Answer-speed and direction
/.acceleration - Answer-change in velocity
occurs when an object speeds up, slows down, and/or changes direction
/.acceleration in same direction - Answer-speed increases
/.acceleration in opposite direction - Answer-speed decreases
/.force - Answer-push or pull
/.net force - Answer-The combination of all forces acting on an object
/.balanced forces - Answer-Equal forces acting on an object in opposite directions, zero
/.Newton's First Law - Answer-An object at rest stays at rest and an object in motion
stays in motion with the same speed and in the same direction unless acted upon by an
unbalanced force.
/.Interia - Answer-The tendency of an object to resist a change in motion
/.action force - Answer-the initial push or pull of one object on another object
/.reaction force - Answer-force acting in the opposite direction
/.friction - Answer-A force that opposes motion
/.kinetic friction - Answer-Friction between moving surfaces
/.static friction - Answer-Friction that acts on objects that are not moving
/.for solid objects - Answer-speed does not affect calculation of force,
what does affect it: types of surface involved and how hard the surfaced press on each
other
