**What do you see?**  Person is pushing someone on a chair with wheels and he is picturing being on a roller coaster. He doesn't know what his coming next.

**What do you think?**  Which part of the roller-coaster ride produces the loudest screams? Why?  I think that the tallest wooden roller coster would produce the loudest scream because people feel as though they may break.

**Look up roller coaster design on the Internet and list at least two roller coasters mentioned. Describe their most important features.**
 * The Comet at The Great Escape in Lake George, NY
 * Wooden
 * It is fast and smooth with little shaking
 * Steel Force at Dorney Park
 * The longest roller coaster on the east coast
 * Top speed: 75mph

PTG
 * Scalar: quantity that has magnitude but no direction
 * displacement: difference in position between a final position and an initial position
 * <span style="color: #ff0084; font-family: Georgia,serif;">depends only on the endpoints, not the path
 * <span style="color: #ff0084; font-family: Georgia,serif;">is a vector quantity that has magnitude and direction
 * <span style="color: #ff0084; font-family: Georgia,serif;">vector: a quantity that has magnitude and direction
 * <span style="color: #ff0084; font-family: Georgia,serif;">speed: distance traveled that has both magnitude and direction
 * <span style="color: #ff0084; font-family: Georgia,serif;">is a scalar quantity that has no direction
 * <span style="color: #ff0084; font-family: Georgia,serif;">velocity: displacement divided by the time elapsed

Displacement is a vector quantity that has magnitude and direction, distance doesn't. <span style="color: #ff0084; font-family: Georgia,serif;">2. 0 <span style="color: #ff0084; font-family: Georgia,serif;">3. Speed doesn't have direction while velocity does <span style="color: #ff0084; font-family: Georgia,serif;">4. You can find an objects acceleration by finding its ∆v and t

<span style="color: #ffb500; font-family: Georgia,serif;">**What do you think now?** <span style="color: #ffb500; font-family: Georgia,serif;">I believe that drops produce the loudest screams and thrills. They are the most unexpected part of the ride and during the drop, riders undergo intense acceleration.
