Unit II: Projectile Motion, Circular Motion & Gravitation

Projectile Motion
	Introduction to projectile motion Introduction to projectile motion
	Monkey and the zoo Keeper This site uses a classic physics problem of the monkey and the Zoo keeper to explain projectile motion and objects in gravity fields
	Projectile Motion lesson
	Newton's Cannon (excellent) This applet is based on Newton's Canon and allows you to manipulate the initial velocity of a cannon ball shot from the top of a high mountain and to view the results.
	Java Cannon Projectile motion of a cannonball being shot at a target giving you control of the velocity, angle, gravity, wind and the density of the ball! Raw Applet: http://jersey.uoregon.edu/vlab/Cannon/index.html Web Activity: http://zebu.uoregon.edu/nsf/cannon.html Game: http://zebu.uoregon.edu/nsf/cannon_alex.html
	Two Cannon Projectile Motion This Java animation shows two cannons firing at each other from different elevations. It shows that if they are pointed at each other even from different heights the projectile paths will always intersect
	Multiple projectiles applet This site allows you to manipulate the initial velocity of a group of projectiles which are launched at all at once at different angles.
Universal Law of Gravity
	Below are several pictures of galaxy types: Galaxy picture Spiral galaxy picture Galaxy cluster
Circular Motion & Kepler's Laws
	Circular Motion notes (Good) This site is a nice basic intro into circular motion with notes and examples.
	Inertia and the right hand turn Inertia's effect on the car's passengers while turning right.
	Circular motion and tension This is a java applet site showing the connection between tension of a open and the mass of an object and how they effect the velocity of circular motion.
	Keplers laws applet (excellent) This site allows you to view planetary motion using all of Keplers laws.
	Satellite (link temporarily down... wrote to author in Grasslands school division.) An orbiting satellite is a projectile in the sense that the only force acting upon is the force of gravity. Also a satellite is acted upon by the force of gravity and this force does accelerate it towards the Earth. In addition, a satellite falls towards the Earth; however, it never falls into the Earth.
Simple Harmonic Motion
	Simple harmonic motion applet (excellent) This sites animation shows a vertical and a horizontal spring and graphs their motion against time showing how both are examples of periodic motion.
	Oscillations in a vertical Spring applet (good) This applet allows you to pull down on a mass at the end of a hanging spring and view the resulting Harmonic motion.
	The Spring Pendulum applet (excellent) This applet allows you to manipulate the angle and length of a pendulum and measure the resulting period JavaPhysMath Appletscopyright
	Simple Harmonic Motion applet (Good) This Java applet demonstrates the variation of elongation, velocity, tangential acceleration, force and energy during the oscillation of a pendulum (assumed with no friction).
	Vibration and Waves Animations This link contains animations which visualize certain concepts concerning Vibration and Waves (sound and light). The choice of animations coincides with topics covered in the courses PHYS-230, Physics III: Waves, and PHYS-480, Fundamentals of Acoustics.
Unit I-II Review
	Unit I-II Review notes CAUTION... the direct link to this site was now passworded. You may try to find what you need in this index. This site is a powerpoint which covers most of Newtons and Keplers laws
	Review notes and quiz (good) This sites will quiz your knowledge of gravity and circular motion
