Δ = change
t = time
tf = final time
ti =initial time
tmotion= Δt – Δtrest
Tres t= t1rest + t2rest + t3rest + t4rest…
Δt = tf - ti
Δ = change
x = position
xf = final position
xi =initial position
DISPLACEMENT
Δx = xf - xi
Pythagora's theorem IF DISPLACEMENT
IS A DIAGONAL LINE
DISTANCE
Δd = ΔxA-B + ΔxB-C + ΔxC-D + ΔxD-A ….
Speed is used to describe an exact
moment in time and determines
how far something moves in a given
amount of time
S= Δd / Δt
or d/t
Average Speed: Is a measurement speed(s)
after the time has lapsed and the distance(s)
have actually been traveled. Even if driving
at 60 m/h at an instant in time, the prior
second the car may have been going 61 m/h
or 59 m/h. Average speed considers all of the
distance(s) traveled and all of the time(s)
used to travel in a calculation.
Savg=
Δx1 + Δx2 + Δx3…
Δt1 + Δt2 + Δt3….
Savg = Δd/Δt
VELOCITY
v is speed with direction.
Example Problem: A LOOK AHEAD

9:00 a.m. on Saturday morning. Three hours later, they pulled over to rest and eat lunch. At
t4
1:00 pm they decided to paddle back to the shore where they parked their car. They arrived
t5
d
at the original shore at 3:00 pm. The total distance traveled was 3 miles. What is the
speed of their entire trip? average speed, and speed while in motion that John and his friend
traveled on the river water? Which way was faster? What is the most logical reason why the
direction was faster?

Creative movement Exercises
Change of Position vs Distance
Students will
•
line up on one side of room
•
Determine position as zero block
•
Count paces via floor blocks to other side of the room
•
Determine position as # of blocks from zero block
•
Determine change of position as # of blocks away from zero block
•
Count paces via floor blocks back to zero block
•
Determine the change in position as the number of blocks away from the zero block
•
Repeat the exercise counting the distance walked as the total number of blocks away from the zero block and back to the zero block
Vector vs scalar Teacher will provide memory strategy of recalling displacements as “from dis place to dat place”
Students will
•
Determine N, S, E, W using a compass or the sun rises in the east and sets in the west
•
Repeat Change of Position but state direction and blocks away from zero block and only return half of the distance back to the zero block.
•
Determine the change of position as a vector measurement and distance traveled as a scalar measurement
Making waves Teacher will provide memory strategy of to crest a hill means to reach the top and pigs eat out of troughs
Students will
•
Form a circle or oval other form where palms can be joined and raised or lowered in alternating sequence forming crests and troughs
•
Change the position of their palms as crests and troughs are pointed to for visualization
•
Groups of 6 will form lines
•
Remaining students will demonstrate the ability to point to the frequency and wavelength formed by their group
•
Groups will switch out the student demonstrator
Creative movement Exercises
Wax on Wane Off
Teacher will provide memory strategy of waxing a car the was turn white before you wipe it so waxing moons are
white from the right and from the movie “Karate Kid” Wax on Wane off, Waning. The sentence White from the right
back to black you never go wrong if you start at the right.
Students will Use white boards, black marker, paper towel while teacher models
•
Draw 4 circles in a T formation
•
Draw 4 circles in a X formation formed between T areas
•
Color the top full circles black
•
Starting at the right T circle label the black circle NEW MOON
•
Going counterclockwise from the New Moon go to the next black circle and erase from the right side a backwards
C to form a waxing crescent
•
Continue counterclockwise to the top of the T and erase from the right half of the black circle label the moon
FIRST QUARTER
•
Continue counterclockwise to the next black circle and erase 3/4 so only a forwards black C remains Label the
moon Waxing Gibbous
•
Continue counterclockwise to the left cross T and erase all of the black then label the moon Full moon
•
Continue counterclockwise to a white moon BACK TO BLACK YOU CAN NEVER BE WRONG IF YOU START AT THE
RIGHT color a black backwards C in the circle and label the moon Waning Gibbous
•
Continue counterclockwise to a white moon at the bottom of the T remember BACK TO BLACK NEVER WRONG IF
YOU START AT THE RIGHT color right half black label Last Quarter
•
Continue counterclockwise to last white moon on the bottom and color all except a forward C black Label moon
Waning Crescent
Teacher should now point out that the upper moons are waxing and correspond one to one with the waning moons
directly below.
Teacher should also point out that moons are quarter moons because we only see one face of the moon ever

Season's change, seasons change,

All through the year.
Tilted TOWARD the sun is summertime,

Tilted TOWARD sun is summertime,

Tilted FAR away is wintertime,
Wintertime, wintertime,
Tilted FAR away is wintertime,
The days are cold and gray.
TILTED in between is spring and fall
Spring and fall Spring and fall
Tilted In-between is spring and fall

Lab X Car Z Car
Combine two affects on speed (1 elevation) and 2 (mass)
Via demonstration prove that a car at a higher elevation travels a greater
Distance than a car at a lower elevation because the speed is increased so through
Manipulation of the equation s=d/t we get (s)(t)=d If the time is held constant then the d for
distance will increase since the car on the higher incline has a greater speed.
Next, students will determine the amount of 240g masses that are needed to show a
Measurable difference between the speed of the x and to z car. Answer 4 masses
Students must complete a minimum of 3 trials per car to obtain an average speed that will be
graphed as distance and time with a starting point at zero.
Students should be able to answer the question: What is the relationship between the distance
of a line from the y axis and the speed of an object.
