Monday: Finish the Free Fall Lab we started in class on Friday.
Tuesday: We will take a test on Tuesday covering the following topics:
I have decided that you will both take this test on the Tuesday of your return.
a) Physics terms: time, distance, displacement, speed, velocity, and acceleration
b) Graphical analysis of the seven states of motion given:
i) position as a function of time – slope analysis
ii) velocity as a function of time – reference to zero m/s analysis, slope analysis, are analysis
c) Data Studio
Wednesday: Introduce Kinematic Equations and Problem Solving Method:
a) Read and take notes from the lesson 6 from the following Physcis Classroom website:
http://www.physicsclassroom.com/Class/1DKin/index.cfm
Thursday work the Sample Problems in lesson 6d.
Friday complete the following attached assignment
A)
D)
B) v =  x
t
vs = d
t
C)
Formula Matching
v= x
t 0
t
a = v – vo or a= V
t - to
t
E) v = v + vo
2
F) v=vo + at
G) x = xo + vot + 1/2 at2
H) v2 = vo2 + 2 a  x
x = vot + 1/2 at2
E) v = v + voy

F) vy=voy + gt
G) y = yo + voyt + 1/2 gt2
H) v2 = vo2 + 2 g y
y = voyt + 1/2 gt2

a) 0 m/s b) 10 m/s c) 20 m/s d) – 20 m/s e) – 9.8 m/s2
9.
A ball is thrown up at 20 m/s. What is its velocity when it returns to the thrower?
a) 0 m/s b) 10 m/s c) 20 m/s d) – 20 m/s e) – 9.8 m/s2
10. A ball is thrown up off a cliff. Which of the following is true?
a) the time it takes the ball to reach its maximum height is the same as the time it takes it to return
from its maximum height to the ground.
b) the time it takes the ball to reach its maximum height is greater than the time it takes it to return
from its maximum height to the ground.
c) the time it takes the ball to reach its maximum height is less than the time it takes it to return from
its maximum height to the ground.
d) the time it takes the ball to reach its maximum height compared to the time it
takes it to return from its maximum height to the ground depends on the velocity
it is thrown up at.
e) the time it takes the ball to reach its maximum height compared to the time it
takes it to return from its maximum height to the ground depends on the height it
was thrown from.
11. Sketch a graph of the position vs time of an thrown up off the cliff
12. Sketch a graph of the velocity vs time of the object thrown up off the cliff from the
time it leaves the throwers hand.
