(intro to language of Kinematics) mechanics: the study of the
motion of objects
(intro to language of Kinematics) Kinematics is the science of describing the …. of objects using …, …., …, …., and ….
motion; words; diagrams; numbers; graphs; equations
(intro to language of Kinematics) kinematics is a branch of
mechanics
(intro to language of Kinematics) the goal of any study of kinematics is to develop …. that describe and explain the motion of real-world objects
sophisticated mental models
(scalars and vectors) the mathematical quantities that are used to describe the motion of objects can be divided into two categories:
scalars/ vectors
(scalars and vectors) scalars are quantities that are fully described by a …
magnitude alone
(scalars and vectors) vectors are quantities that are fully described by a …
magnitude and a direction
(distance and displacement) distance is a … quantity that refers to “how much …. an object has ….” during its …
scalar; ground; covered; motion
(distance and displacement) displacement is a … quantity that refers to “how far …. an object is”: it is the object’s overall ….
vector; out of place; change in position
(distance and displacement) displacement must give attention to
direction
(distance and displacement) vector quantities such as displacement are
direction aware
(distance and displacement) scalar quantities such as distance are ignorant of
direction
(Speed and Velocity) speed is a … quantity that refers to “how … an object is …”
scalar; fast; moving
(Speed and Velocity) speed can be thought of as the rate at which an object
covers distance
(Speed and Velocity) a fast-moving object has a …. speed and covers a relatively … distance in a short amount of time. the opposite is true
high; large
(Speed and Velocity) an object with no movement at all has … speed
zero
