7.1  Linear Momentum

Momentum and Its Conservation

This is the Physics Classroom lesson on momentum and its conservation. It includes a tutorial, a self-check quiz, and real-world applications.

Linear Momentum

This page from Bang! Boing! Pop! provides a tutorial on linear momentum and includes a link to a self-check quiz. (Click "Visit Site" if the "Oracle Thinkquest" page appears.)

Impulse

Impulse in stopping a car

Momentum

A discussion of momentum using a simulation of football players colliding. You can change the velocity of the football players and see how the play changes.

Momentum Effects on Aerodynamic Forces

This NASA site discusses momentum effects on aerodynamic forces. It includes a link to a Java simulation that allows you to investigate how an aircraft wing produces lift by changing the values of different factors that affect it.

The Physics of Baseball

This site discusses the path and range of a baseball in terms of Newton's laws. A click on the word momentum in the text will take you to a more in-depth discussion of the role of momentum in baseball.

How Air Bags Work

A discussion from How Stuff Works about air bags in automobiles. The second page deals with momentum in auto accidents.

Newton's Cradle

A simulation of Newton's cradle. Students can observe the conservation of momentum.

The Physics of Football

This page from the How Does the Physics of Football Work? site discusses how tackling and blocking runners rely on three important principles of physics: impulse, conservation of momentum, and rotational motion.

The Physics of Bouncing Balls

A more advanced view of two balls bouncing "vertically in line" with each other under the effect of gravity. The user can vary the ratio of the two masses, plotting points for v to x. The Poincare graph appears to be "chaotic" as slight changes in the ratio of masses produce some very interesting patterns on the graph (unclick the "animation" to speed the graph generation).

Explosions and Momentum

Conservation of momentum in explosions

Gun Recoil

Gun recoil in terms of momentum conservation

Conservation of Momentum Experiment

Instructions for an experiment demonstrating the conservation of momentum. The experiment requires use of an air track and two photogates.

 

7.2  Angular Momentum

Angular Momentum

This page gives a tutorial on angular momentum and includes a link to a self-check quiz. (Click “Visit Site” if the “Oracle Thinkquest” page appears.)

Angular Momentum and Area

This simulation demonstrates that the angular momentum of an object moving in a straight line will remain constant with respect to a fixed point.

Black Holes

This site discusses the two types of black holes—Schwarzchild and Kerr—and uses rotation as the distinguishing factor. Kerr black holes rotate because the stars from which they were formed rotated.

Tornadoes

A How Stuff Works site describing tornadoes and how they are formed. It includes links to several other informative sites related to tornadoes.

The Science of Jumping and Rotating

Part of Montana State University's course on winter Olympic sports. In particular, pay close attention to the lesson on Conservation of Angular Momentum.

Conservation of Angular Momentum

This site uses a Java applet of a swinging pendulum to demonstrate the conservation of angular momentum.
