2. Mini Metric Olympics
Olympic Symbol: five interlocking rings represent the five major continents of the world. Their colors in order from left to right are blue, yellow, black, green, and red. These colors are special because at least one of them appears in the flag of every nation of the world. These colorful rings are joined together to remind us of the sporting friendship of all mankind.

3. History: Ancient Games: Traditionally the accepted date of the first Olympiad is 776 BC but there is reasonable certainty that they were held considerably earlier than that. These festivities were held in Olympia, Greece where a stadium and a temple to Zeus were built. On selected occasions a “day of games” was held to honor a god or a dead hero. Only males were allowed to participate and events originally included a foot race, wrestling, and the pentathlon which was a combination of five events. The ancient games ceased to take place after 392 AD because they were viewed by Christians as a pagan ritual.

4. The Olympic Motto: Citius, Altius, Fortius from the Latin meaning swifter, higher, stronger. These words are used to build healthy attitudes and winning spirits in preparation for competition.
The Olympic Flame: The Olympic Flame is lighted by the Olympic torch during the opening ceremonies. The flame is a symbol of peace and is lit first in the temple of Zeus in Olympia. Thousands of relay runners from many countries then carry it to the stadium of the city hosting the games. The flame is passed by hand from one runner to the next.

5. Modern Olympic Games: Credit for the revival of the Olympic Games goes to Pierre de Coubertin, a French baron who felt strongly about bringing together representatives from many nations for the purpose of peaceful competition. He posed these words that now make up the Olympic creed: “The most important thing in the Olympic Games is not to win but to take part, just as the most important thing in life is not the triumph but the struggle. The essential thing is not to have conquered but to have fought well.” With respect and honor to Greece, the land of

6. the original games, the first modern games were held in Athens in 1896 where nine countries came together. The Olympic Games were held in Seoul, south Korea where 161 countries competed in 23 Olympic sports. Winners in each event earned gold, silver, and bronze medals for their performances. Each athlete made this pledge: “We swear that we will take part in these Olympic Games in the true spirit of sportsmanship and that we will respect and abide by the rules which govern them for the glory of the sport and the honor of our country.”

18. Kinematics
The science of describing the motion of objects using words, diagrams, numbers, graphs, and equations.
How do we describe motion in words?
In physics, we will be expanding our word descriptions to include: distance, displacement, speed, and velocity.
As you will soon see, these words are associated with mathematical quantities which can be divided into two categories.

19. Scalar – quantities fully described by a magnitude (numerical value) alone.
Vector – quantities fully described by both a magnitude and a direction.
Distance – a scalar quantity that refers to how much ground an object has covered.
Displacement – a vector quantity that refers to how far out of place an object is; its overall change in position.

20. 4m 2m 2m A physics teacher walks 4 meters West, 2 meters South, 4 meters East, and finally 2 meters North. Distance = 12 meters Displacement = 0 meters

21. Practice Find the distance and the displacement.
A) Cross-Country Skier:
In the first minute, the skier travels 180 meters East.
In the second minute, the skier travels 140 meters West.
In the third minute, the skier travels 100 meters East.
B) Football Coach (pacing the sidelines):
In the first three minutes of the game, the coach paces 35 yards West.
In the next three minutes, the coach paces 20 yards East.
In the next four minutes, the coach paces 40 yards West.

22. Speed – a scalar quantity that refers to how fast an object is moving
Speed – a scalar quantity that refers to how fast an object is moving. (miles/hour)
Speed can be thought of as the rate at which an object covers distance.
No movement = zero speed
Velocity – a vector quantity that refers to the rate at which an object changes its position. (miles/hour + direction)
Velocity is the rate at which an object changes position.
If a person returns to their original position, they have zero velocity. Every step must go into moving a person further from their original position.

23. Slope
m = 𝑦 −𝑦 𝑥 −𝑥
The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points.
Pick two points on the graph and determine their coordinates.
Determine the rise by subtracting the y-coordinates.
Determine the run by subtracting the x-coordinates.
Divide the rise by the run.

24. Math Slope vs. Science Slope
In Math, the slope is written as a numerical value. It is generally left in fraction form.
In Science, the slope is written as a numerical value with units. It is not left in fraction form-it is simplified. These units come from the graph and represent a rate.
Example:
X-axis is time (in seconds)
Y-axis is distance (in meters)
Slope is speed (in meters/second)

25. Slope and Graphs
Find the slope for the following graphs:

26. Slope Equations in Math and Science
In Math, the equation for the slope of a line is a numerical value in the following format:
y = mx + b
y = 2x + 3
In Science, the values for y and x are written as measurement values. The values for m and b are written as numerical values with units.
distance (m) = 2 m/s × time (s) + 3m
