An online course in particle physics with colorful images, charts and animations. Begin by learning about the Standard Model and the types of particles, particle families, and forces, then carry this knowledge over to your study and...

What happens when a snowball hits a huge ball of gas? When Comet Shoemaker Levy 9 hit Jupiter, it was swallowed up in the atmosphere, leaving huge temporary impact scars. Here is an image that shows the large dark marks and how they...

This page discusses the many different cultures that came to California during the gold rush.

Observe the reaction when a buckyball collides with a neon crystal.

Young scholars investigate the best way to cushion wrap a sugar cube to protect it from a collision in this lesson plan. During their investigation, students learn about collisions and variables that affect collisions.

Try to predict what will happen in three different bumper car collisions. For each collision, you'll be shown two possible outcomes.

In this interactive physics tutorial, students will take a more qualitative approach to some collision problems. The questions provide a real test of conceptual understanding of momentum conservation in collisions.

This study guide on momentum defines some key terms and discusses the Law of Conservation of Momentum, elastic and inelastic collisions, and how impulse relates to momentum. Includes equations and two example problems with solutions. It...

Students explore impulse and momentum. Some topics examined in the activities are collisions, impulse, Newton's laws, and momentum. The resource consists of lecture notes, practice problems, and exam questions. Practice problems and exam...

Students explore center of mass. Some topics examined in the activities are collisions, center of mass motion, and power. The resource consists of video clips, lecture notes, practice problems, and exam questions. Practice problems and...

In this physical science related activity, students will use inquiry skills and investigative procedures to determine which vehicle is at fault in a collision between a car and tractor-trailer.

In this guided inquiry demonstration, a person on rollerblades and a medicine ball are used to teach the concept of conservation of momentum. Various sorts of collisions are used to show how momentum is conserved within a system.

Students learn about the physical force of linear momentum - movement in a straight line - by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological...

In this physics tutorial, the law of momentum conservation will be combined with the use of a momentum table and some algebra skills to solve problems involving collisions occurring in isolated systems.

Students learn that total system momentum is conserved for collisions occurring in isolated systems. They will find out what makes a system of objects an isolated system, and whether momentum conserved if the system is not isolated.

Students must predict the amplitude and frequency of oscillation for a hovercraft getting stuck to a spring.

Students must calculate the impulse given to a hockey puck by the boards. The puck will collide with the boards and bounce off in the opposite direction.

This lab activity from the Illinois Institute of Technology lets students investigate the impact of collisions upon the velocity and momentum of the colliding objects. Requires understanding of vectors.

From ABC News in Science, Larry O'Hanlon's article on black hole collision discusses the process of the collisions and the means by which scientists track and collect data from these collisions.

A site dedicated to help students prepare for the AP Physics B test. This specific site reviews the conservation of momentum including impulse, elastic and inelastic collisions, linear momentum, and center of mass. Site contains links to...

From ABC News in Science, Heather Catchpole's article explores issues related to the collision of galaxies and the subsequent formation of black holes.

From ABC News in Science, Larry O'Hanlon's article examines scientific evidence which suggests that the death of our solar system will be linked to the collision of comets.

After a dramatic introduction to the "Love affair," between Earth and Theia, this site gives support to the claim that the moon was created by a collision between these two planets. Also contains a brief bibliography.

SkyServer explains and presents images of spiral galaxies, elliptical galaxies, irregular galaxies, galaxy clusters, galaxy collisions and the like.
