Which of the following is a vector quantity meaning "how far out of place an object is" and
overall change in position?
a. distance
b. displacement - ANS b. displacement
Which of the following is a scalar quantity meaning "how fast an object is moving," rate at
which an object covers distance, *distance/time*, and is ignorant of direction?
a. speed
b. velocity - ANS a. speed
Which of the following is a vector quantity meaning "the rate at which an object changes its

,a. speed
b. velocity - ANS b. velocity
What vector quantity is the rate at which an object changes its velocity, *change in
velocity/time*? - ANS acceleration
What are the 2 things that direction of the acceleration vector depends on? - ANS whether
the object is speeding up or slowing down and whether the object is moving in the + or -
direction
Which of the following is a *scalar quantity* referring to the *amount of matter* that is
contained by the object or how much stuff is present in the object?
a. mass
b. weight - ANS a. mass
Which of the following is a *vector quantity* meaning the force of gravity acting upon an object
or the force with which gravity (Earth or any other planet) pulls upon stuff that is present in an
object?
a. mass
b. weight - ANS b. weight
What is a *vector quantity* which is referred to as "mass in motion," the quantity of *motion*
an object possesses, or *= mass x velocity*? - ANS momentum (p)
*TQ: What vector quantity is an action (push or pull) upon a body causing it to deform or
move? - ANS force
•also note force is measured in Newtons (N)
Copyright ©2025 BRIGHTSTARS ALL RIGHTS RESERVED 3
, What is the equation for force? - ANS Force = Mass x Acceleration
•remember *mass* is a quantity of matter that makes up a sample and *acceleration* is a
change in velocity over a unit of time

ANS inertia
Which of the follow best describes the 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?
a. Newton's First Law of Motion
b. Newton's Second Law of Motion
c. Newton's Third Law of Motion - ANS a. Newton's First Law of Motion
Which of the follow best describes that a system in *equilibrium* is either at rest or moving
with a constant velocity?
a. Newton's First Law of Motion
b. Newton's Second Law of Motion
c. Newton's Third Law of Motion - ANS a. Newton's First Law of Motion
