PHYSICAL SCIENCE
Change in velocity divided by the time it takes for the change to occur --
ANSWER--Acceleration
Speeds up
Slows down
And/or
Changes direction -- ANSWER--Acceleration occurs when an object
A push or pull exerted on an object -- ANSWER--Force
Newton (N) -- ANSWER--SI unit for force
The combination of all forces acting on an object -- ANSWER--net force
forces acting on an object that combine and form a net force of zero --
, Page 2 of 118
ANSWER--balanced forces
Forces that produce a nonzero net force, which changes an object's motion --
ANSWER--unbalanced forces
(An object continues in uniform motion in a straight line/ at rest unless a
resultant force acts.)
The net force on an object is the cause of its acceleration -- ANSWER--
Newton's First Law
The tendency to keep the same motion- remaining at rest or maintaining the
same velocity -- ANSWER--Inertia
The acceleration of an object depends on the mass of the object and the amount
of force applied.
F=ma -- ANSWER--Newton's Second Law
For every action there is an equal and opposite reaction -- ANSWER--Newton's
Third Law

The force that two surfaces exert on each other when they rub against each other
-- ANSWER--Friction
The force of friction between two objects that are moving against each other --
ANSWER--kinetic friction
frictional force that prevents two surfaces from sliding past each other --
ANSWER--static friction
A force of attraction between objects that is due to their masses. -- ANSWER-
Gravity
mass times velocity -- ANSWER--linear momentum
Momentum is conserved when two or more objects collide. Momentum may
transfer but total momentum within the group stays the same -- ANSWER--Law
of conservation of momentum
The study of the properties of matter and how matter changes; atoms, molecules
and their interactions to form substances -- ANSWER--Chemistry
, Page 4 of 118
the study of the moon, stars, and other objects in space -- ANSWER—
astronomy
The study of energy and forces of matter -- ANSWER--Physics
The scientific study of earth and the universe around it including structure,
materials and processes -- ANSWER--Earth Science
The experimental factor that is manipulated; the variable whose effect is being
studied. -- ANSWER--independent variable
The measurable effect, outcome, or response in which the research is interested.
-- ANSWER--dependent variable
Structures that scientists build to represent something else. -- ANSWER--
Physical Model
a verbal or graphical explanation for how a system works or is organized --
ANSWER--conceptual model
