Introduction:

﻿You will be provided with various links to websites that will help to to gain a better understanding of projectile motion. These websites will help you define the important vocabulary terms associated with projectiles and provide supporting examples of the different types of projectiles. You will then create your own application of a projectile and display your work on a poster that will be presented to the class.

Before you get started use the following prezi to familiarize yourself with the basic shape that a projectile makes. After viewing the pictures and video consider where you see the path of a projectile (parabola's) in your everyday life. Then compile your own images and video clips and create your own prezi that illustrates these ideas.

﻿Process:

(1) Use the given websites to answer the bullets that follow:

http://www.physics247.com/physics-tutorial/projectile-trajectory.shtml
http://www.cramster.com/definitions/projectile-motion/665

http://tutorial.math.lamar.edu/Classes/Alg/Parabolas.aspx
http://www.mathwords.com/p/projectile_motion.htm

- Define projectile, projectile motion, trajectory, parabola, and vertex.- Briefly describe Galileo's theory on projectile motion.- Give a few examples of projectiles.- Explain why birds and airplanes are NOT projectiles.- Identify the formula for the height of a projectile.

(2) The following simulations show the path of a projectile. Both the plane and the truck are moving at a constant speed.

(3)Each group must create an application problem similar to those done in class.

Possible Topics: All projects need a starting height above the ground ( i.e. s ≠ 0 ). Values for initial velocity (Vo) and starting height need to be accurate to the real life situation (look values up if you are not sure!)
Sport Projectiles Evironmental Projectiles Man-Made Projectiles
A diver diving from platforms Volcanic Eruption Cannon Balls from a ship
A baseball hit or thrown Bird catching pray Bomb dropped from an aircraft
A football kicked or thrown Water balloon dropped
A basketball shot into a hoop

v Each group must draw a diagram of the situation on the front side of your project, along with the description of the situation (typed) – label all parts of your graph, including the key points on the graph. Make certain that you label units of these measurements. *Be sure to display general equation in terms of feet or meters*
v ON THE BACK of the poster – each group must draw another diagram (this does not have to be as elaborate as the diagram on the front of your project) with the correct answers labeled on it. Along with this diagram, each group must include an algebraic EXPLANATION of how you attained your solutions – show work and explain. At a minimum, you must determine:
a) The maximum height
b) The time at which the maximum height occurs
c) The time at which the object returns to Earth
d) Starting point
e) Any other significant point (i.e. ball going through a 10 ft. net)
v You will also hand in a sheet of paper explaining how each group member contributed to the project. Each member needs to have contributed to some aspect of the final product. All members will be responsible for understanding the math.
