G. Two objects appear at the same place (15 cm) at 1 second, one disappears at 20 cm at 2 seconds while
another appears at x = 0, both disappear at same location at 3 seconds. (Cannot reproduce with
motion sensor. Not a function.)

K. Initial velocity = zero, acceleration is positive and increasing to about +1 cm/s/s.
L. Initial velocity = zero. For first 2 seconds, acceleration =-2 cm/s, from 2-3 seconds, acceleration = +4
cm/s; after t = 3 seconds, both velocity and acceleration are zero.

M. Acceleration is initially negative, changes to zero. Initial velocity = 4 cm/s, decreases to about -1.5
cm/s.
N. Initial velocity = 4 cm/s. Acceleration is initially negative, changes to zero by 3 seconds and remains
zero. Final constant velocity = +1.5 cm/s.
0. Initial velocity = -2 cm/s, is constant for first 2 seconds. Then there is a constant acceleration of
+1.33 cm/s as velocity increases to 2 cm/s.

Transcribed Image Text:1.
For each of the following graphs, discuss with your team and think of a motion that would create the graph.
Be sure that you can accurately describe the velocity and acceleration for each motion.
2.
Your team will be assigned two motions. Write a detailed description of the motions, with enough detail so
that someone can follow your instructions and recreate the graph.

D. Velocity changes from 0 to +5 cm/s. Acceleration is positive, and constant (if the position vs. time curve
is parabolic.) Initial position = 3 cm.
E. Velocity and acceleration are both changing and alternating from positive to negative, initial position =
10 cm, alternates from 15 cm to 5 cm.
F. Starting from origin, nearly constant velocity of about +17 cm/s for the first second, then changes to
negative velocity. Acceleration changes from zero (first second), to negative, to positive (at about 2
seconds). Object "disappears" or data is lost from 3 - 4 seconds.
