  1. Given all the walking about the gardens of the Palikir campus, in keeping with our Aristotlean first day, what school of Grecian thought might you call yourselves?

    The ______________________________ school
  2. Two qualities must be present for density to exist. Name the two qualities:

Time versus space, space versus space graphs text layers Graph 1 Graph 2 time: duration (seconds) space: distance (cm) east-west space: distance (cm) space: dist (cm) north-south

  1. What does the line with the points on graph 1 represent?
  2. What do the three lines on graph 2 represent?

Arc of a sphere text layers Graph 3: Arc of a sphere (ball) through the air space: distance (cm) space: distance (cm) r = 200 cm k = 200 cm y = − ( k r2 ) x2 + k

  1. _______________ What is the name of the shape of the arc (curve) seen on graph 3?
  2. y = _______________ Given graph 3 and the equation shown on graph 3, if x = 50 cm then what does y equal?
  3. Why does a ball moving through the air follow the curved arc seen on graph 3?

Marble rolling Graph 4: Rolling marble (0.75 s, 30 cm) (0 s, 0.0 cm) time (s) distance (cm)

  1. ____________________ A marble was rolled as seen on the graph 4. What is the nature of the mathematical relationship between time and distance?
  2. ____________________ A marble was rolled as seen on graph 4. What was the velocity of the marble?
  3. ____________________ Given that the marble above has a mass of 5 grams, what is the momentum P⇀ of the marble in graph 4?
  4. ____________________ Using the formula v=40h determine the velocity v for a marble rolling on a table launched from a height h of 169 cm on a banana leaf.
  5. ___________________ What exerts more force given an equal application of pressure: a small surface or a large surface?
  6. ___________________ What is the temperature of a mix of melting ice and water in Celsius?
  7. ___________________ What is the typical daily room temperature in Pohnpei in Celsius?
  8. ___________________ What is the temperature of a boiling water in Celsius?
  9. ___________________ What are the three ways in which heat moves?
