Hypothesis

A statement that says something about how you expect the world to work
 must be testable must be able to be proven wron 

Inquiry Cycle

QuestionPredictionExperimentsModelApply
A scientist may jump from any point of the inquiry Cycle 

Model

Set of rules, so that if we follow them, we will get the tight answer. Allows us to answer questions the same way as the Universe, but we do not know how the Universe answers them


Speed

How fast :
distance  time 

Relative Motion

Reference Frame (point of view)
ground egocentric heliocentric 

Average Speed

distance
 time or initial + final  2 

Average velocity

displacement
 time 

Constant Velocity

same speed, same direction (in a straight line)


Change in Velocity

turning, slowing down, speeding up


Acceleration

Any change in velocity
Rapid Cahnge: big, fast acc Gradual Change: Small, slow acc Change in Velocity  = a = ^v/t Time = final  intial  Time 

Change in Velocity

Acc * time


Distance

average speed * time


Distance (Position Graph)

speed=slope
straight line=constant velocity curved line=acc corners= impossible to recreate because one can;t make a change in speed in no time 

Velocity Graph

Graph:


Slope
(Position and Velocity Graphs) 
Slope amount of change in what we're graphing
Postion graph slope will be change in position vs. time (speed Velocity Graph Slope will be change in velocity vs. time (acc) 

Graph Patterns

Positive Acc

speeding up (+) moving away (+)
slowing down () moving toward () 

Negative Acc

Moving towards () speeding up (+)
Moving away (+) slowing down () 

Instantaneous Speed

Speed at that exact moment


Final Speed

initial+ change in speed


Change in Speed

acc * time
final initial  time 

Free Fall

Motion under the influence of gravity
 no air resistance ect. allowed  not necessarily falling down  all objects fall at the same rate (Galileo) 

Acc due to Gravity

g= 9.8 m/s2 = 10 m/s2


d=1/2gt2

Falling from rest
Not things that are thrown ex:  falling 2 times as long 4 Times as far 

Science vs. Technology

Science way of knowing
Technology way of doing 

Science vs. Religion

Science Cosmic Order
Religion Cosmic purpose
