NES Subtest 2 UPDATED Exam Questions
and CORRECT Answers
solid - CORRECT ANSWER - molecules that are closely bound to one another by
molecular forces. Holds definite shape and the volume is fixed by its shape
liquid - CORRECT ANSWER - molecular forces are weaker than in a solid and maintains
its volume but takes the shape of its container
gas - CORRECT ANSWER - molecular forces are very weak, so it takes the shape of the
container and expands to fill the container.
newtons first law - CORRECT ANSWER - an object at rest will remain at rest and a body
moving with a constant speed in a straight line will maintain its motion unless acted upon by an
unbalanced external force
newtons second law - CORRECT ANSWER - the greater the mass of the object being
accelerated, the greater the amount of force needed to accelerate the object.
newtons third law - CORRECT ANSWER - all forces in the universe occur in equal but
oppositely directed pairs; for every action, there is an equal and opposite reaction.
inclined plane - CORRECT ANSWER - a slanted surface, such as a ramp, used to raise an
object.
wedge - CORRECT ANSWER - an inclined plane which moves
screw - CORRECT ANSWER - an inclined plane wrapped around a cylinder to form a
spiral
, lever - CORRECT ANSWER - three parts: a fulcrum, an effort arm, and a resistance arm
pulley - CORRECT ANSWER - a chain, belt or rope wrapped around a wheel
wheel & axle - CORRECT ANSWER - a lever that rotates in a circle around a center
point, or fulcrum
amplitude - CORRECT ANSWER - A measure of the distance between a wave's crest and
trough
frequency - CORRECT ANSWER - The number of oscillations the wave undergoes in a
certain amount of time
static electricity - CORRECT ANSWER - the result of an imbalance between negative and
positive charges in an object
current electricity - CORRECT ANSWER - This comes from a stream of electrons moving
through the conductor
magnet - CORRECT ANSWER - any object that has the ability to attract ferrous objects
like iron, steel, nickel, and cobalt
energy - CORRECT ANSWER - the ability to work
chemical energy - CORRECT ANSWER - Energy stored in bonds of atoms and molecules
EX: Gasoline & Coal
electrical energy - CORRECT ANSWER - produced by the movement of electrically
charged particles (electrons). The movement of electrons through a conductor, such as a wire, is
called current (or circuit) electricity.
