  1. Science Starter! A frustrated student drops a book out of a window that is 18 m above the ground. A curious student below notices that it takes 1.92 s for the book to reach the ground. (a) Draw and label a diagram of the scenario. (b) Determine the accelerationof the book, rounding to one decimal place, assuming it was dropped with zero initial velocity. (c) Determine the final velocity of the book just before it hits the ground.

  2. Free Fall Section 3.3

  3. “Terminal Velocity” Listen for and record the following information: ‘Fall Time’ ‘Fall Distance’

  4. Determine: (a) The fall distance in meters. (b) The acceleration of the rider (m/s2) (c) The velocity of the rider as he/she hits the net.

  5. Free-Fall • Object starts at rest (vo = 0 m/s) - In equations, “y” is used for distance (not “x”). • Object falls solely under the influence of gravity (Resistive forces of air resistance are ignored) Acceleration due to gravity: ag = - 9.8 m/s2 “g” = 9.8 m/s2

  6. “Drop of Doom” • How fast will the ride be traveling when it hits the ground, in m/s? • How fast is this in mi/hr? • How long will the drop last?

  7. Galileo Galilee • Father of Modern Science • Refuted Aristotle’s “Natural Motion” theory • Supported Copernicus’ heliocentric model of the solar system A brief biography...

  8. Does ‘weight’ matter?
