"Six Flags" Field trip questions


Individual ride questionnaire:
Name of the Ride:___________________________________________________
1.- Does it use Potential and/or Kinetic energy?
2.- Why don’t rollercoasters fall down whilst in a loop?*
3.- Which forces are at work in the ride?
-Gravity
-Magnetism
4.- Why is this ride fun?
5.- How does the ride come to a stop?
6.- Is this the strongest ride in the park?
7.- What is the speed of the ride?
8.-  What is the pull or push felt right before a ride begins?
9.- How many “G’s” do we experience in the ride?
10.- Describe the sensations experiences during the ride.
11.- What is the maximum height of the ride?

General Questionnaire:
1.- Which was the first ride built in the park? Was it fast?
2.- How does the Superman use magnets?
3.- Kilauea: When you begin your downward movement, does the ride push down or is it only gravity pulling down?
4.- Why do we experience changes in speed during the ride?
5.- How fast does the superman ride move?
6.- Why is there a motor at the top of the Boomerang ride?
7.- Why do you feel like flying in the Superman ride?
8.- What are “G’s”?
9.-Can a rollercoaster kill you?
10.- Why does Splash mountain move so much water?
11.- Who designs and builds the rides in the park?

Logic gates

Logic gate

From Wikipedia, the free encyclopedia
A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logical inputs, and produces a single logical output. Depending on the context, the term may refer to an ideal logic gate, one that has for instance zero rise time and unlimited fan-out, or it may refer to a non-ideal physical device[1] (see Ideal and real op-amps for comparison).
Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. With amplification, logic gates can be cascaded in the same way that Boolean functions can be composed, allowing the construction of a physical model of all of Boolean logic, and therefore, all of the algorithms and mathematics that can be described with Boolean logic.
Logic circuits include such devices as multiplexers, registers, arithmetic logic units (ALUs), and computer memory, all the way up through complete microprocessors, which may contain more than 100 million gates. In practice, the gates are made from field-effect transistors (FETs), particularly MOSFETs (metal–oxide–semiconductor field-effect transistors).
Compound logic gates AND-OR-Invert (AOI) and OR-AND-Invert (OAI) are often employed in circuit design because their construction using MOSFETs is simpler and more efficient than the sum of the individual gates.[2]
