PROJECTILE+MOTION+VOCAB+GROUP+2

[[t**oc|]**

Directions: 1.) For each word develop a definition written in "7th grade terminology". Do not use any words that you do not understand. 2.) Also add images by linking to them (your teacher will show you how to do this) and annotating these images. Your images should be smaller than the area of a playing card. 3.) Finally, add links to resources that help explain the word. Annotate each link. 4.) Citations, citations, citations...MLA FORMAT!Need an Example Vocab Word Entry (Click Here)

1.) Definition (s)
Definition 1- Parabolic Motion is the curved path a projectile, or an object, follows during its flight. Citation 1- Ruchi

Definition 2- A path a projectile follows when two forces are acting on the projectile: vertical motion and horizontal motion Citation 2- Thomas W.

2.) Images with Annotation
Image 1: Image 1 Annotation: This picture shows a diver who is jumping off of a diving board. He is moving in a parabolic motion; or a curved path. Image 1 Citation: 6 Sep 2007 <[|http://img.sparknotes.com/content/testprep/bookimgs/sat2/physics/0005/diver.rote.gif>.]

1.) Definition (s)
Definition 1- Air resistance is the wind effect on the projectile. Citation 1- Ruchi

Definition 2-Air resistance is a variable that affects the speed and velocity of a projectile. Air resistance can cause drag on an object while falling. This drag could decrease the speed at which gravity pulls it down. Citation 1- C, Grant

Definition 3-Air resistance is the collision of the surface of the object and the air molecules. One of the things that affect air ressisance is the speed of the object. Citation 2- Henderson, Tom. "Lesson 3: Newton's Second Law of Motion." __Free Fall and Air Resistance__. 1996-2007. 5 Sep 2007 <[|http://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/newtlaws/u2l3e.html>.]

Image 1 Annotation: The parachute that is larger provides the faller with more air resistance Image 1 Citation: Henderson, Tom. "The Physics classroom tutorial." 09/05/2007 6 aug 2007 <[|http://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/newtlaws/u2l3e6.gif>.]

Image 3: Image 3 Annotation: This is showing how since the elephant goes faster then the feather because one it's heavier so it goes faster and it has less air resistance since it goes faster, the feather on the other hand is going slowly so the air resistance works more on it.

Link 1-[|Click here to go to a simulation that shows air resistance's effect on an object.] Link 1 Annotation-This simulation has the option of having/not having air resistance while launching the projectile and shows air resistance's effect on the projectile. Link 1 Citation-

Link 2- [|Click here to learn about Newton's Law] Link 2 Annotation- This website teaches all you need to know about air resistance. Link 2 Citation-http://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/newtlaws/u2l3e.html

1.) Definition (s)
Definition 1- A variable is an object/thing that can change. There is an independent variable and a dependent variable. The dependent variable is on the y axis and gets changed. The independent variable is on the x axis and never gets affected by an experiment.

Definition 2-A //variable**// is //any entity that can take on different values//. Citation 1- http://www.socialresearchmethods.net/kb/variable.php

3.) Links with Annotation
Link 1-[|Click here to begin a projectile motion game with changeable variables.] Link 1 Annotation-In the linked game, you can change the path which a water balloon follows by changing the gravity, wind resistance, velocity, and the angle.

1.) Definition (s)
Definition 1- Forces acting on a moving object that slows the object down. For example, when you rub your hands together, the ridges are acting like brakes that help slow the other hand down. The energy between the two objects creates heat.

Citation 1- B, Ian “My Brain”

Definition 2- A resistive force acting between two bodies that opposes movement. Citation 1- Weisstien, Eric. "Friction -- from Eric Weisstien's World of Physics." __Eric Weisstien's World of Physics__. 6 9, 2007. 6 Sep 2007 <[|http://scienceworld.wolfram.com/physics/Friction.html>.]

1.) Definition (s)
Definition 1- Range is the area an object covers during its flight. Citation 1- Ruchi

1.) Definition (s)
Definition 1- Distance is a measurment of the length an object is, or where an object landed if thrown. Citation 1- Ruchi
