Represent and analyze the motion of an object
graphically.
Analyze the velocity of two objects in terms of
distance and time (i.e., verbally,
diagrammatically, graphically, mathematically).
Measure and analyze an object’s motion in terms
of speed, velocity, and acceleration (i.e., verbally,
diagrammatically, graphically).

A. To describe motion accurately and
completely, a
_frame_
of
_reference__
is
necessary.
A
_frame_
of
_reference_
is a system of
_objects_
that are
_not_
moving
with respect to one
another.
Who’s moving faster???

B.
_Relative_
motion is movement in
relation to a
_frame_
of
_reference_
.
For example, as a train moves past a
platform, people
_standing_
on the
platform will see those on the train
_speeding_
by.
But when the people on the
_train_
look
at one another, they don’t seem to be
_moving_
at all.

_
Distance_
is the length of a
_path_
between two
_points_.
D. Distance is the
_length_
of the path
between two
_
points
_.
_Displacement_
is the direction from the
_starting_
point and the
_length_
of a
straight line from the starting point to the
_ending_
point.
