Unit 1: Introduction to Physics
Science - correct answer ✔The use of knowledge in a organized and
classified manner.
Natural Science - correct answer ✔The study of the universe and its
contents.
Velocity - correct answer ✔Speed
Rate of change of position of an object over time
Inertia - correct answer ✔Property of matter that resists its change in motion.
Tendency of a resting body to remain at rest and the tendency of a body
moving at a constant speed in a straight line to continue its states of motion.
Force - correct answer ✔Push or pull of an object.
Newton (N) is the SI unit of force.
Mass - correct answer ✔Quantity of matter.
Measure of Inertia.
Physical Science - correct answer ✔The study of nonliving matter
Physics - correct answer ✔The branch of physcical science that studies
matter and energy and their relationships.
Biological Science - correct answer ✔The study of living matter
, Scientific Method - correct answer ✔Comprises the systematic collection of
facts, the study of their interrelationships, and the drawing of valid conclusions
from the resulting data.
Law of Inertia (1st Law) - correct answer ✔A body will remain at rest or if in
motion will continue moving at a constant velocity in a straight line unless
acted upon by an external force
Law of Force (2nd Law) - correct answer ✔The force acting on a body is
proportional to its mass times acceleration; the direction of the force is the
same as that of the body's acceleration.
F=ma - correct answer ✔Newton's Law of Force equation.
F=Force
M=mass
A=acceleration
Law of Action/Reaction (3rd Law) - correct answer ✔For every action there is
an equal and opposite reaction
Powers of Ten - correct answer ✔A system used to express large and small
numbers too cumbersome to write in ordinary notation.
Decimal Point - correct answer ✔A dot that separates the ones digit and the
digit immediately to its right
Decimal Numbers - correct answer ✔Numbers to the right of the decimal
point.
