The objective of this lesson is to illustrate how a common everyday experience (such as playing pool) can often provide a learning moment. In the example chosen, we use the game of pool to help explain some key concepts of physics. One of these concepts is the conservation of linear momentum since conservation laws play an extremely important role in many aspects of physics. The idea that a certain property of a system is maintained before and after something happens is quite central to many principles in physics and in the pool example, we concentrate on the conservation of linear momentum. The latter half of the video looks at angular momentum and friction, examining why certain objects roll, as opposed to slide. We do this by looking at how striking a ball with a cue stick at different locations produces different effects.

Though not required, students who have been exposed to some physics would benefit most from this video. In mathematically rigorous classes, students can concentrate on the details of vectors and conservation of linear momentum.

This lesson provides an introduction to Pressure, Temperature and Gay-Lussac's Gas Law, using as an example the Deflategate controversy that took place in the sport of American Football in January 2015. The main learning objectives are: (1) to define temperature and pressure; (2) to introduce the concepts of absolute pressure and absolute temperature, including the use of Kelvin measurement units; (3) to use Gay-Lussac's law to predict how the pressure of a fixed container of gas, such as a football, will change due to an increase or decrease in temperature; (4) to compare predictions from a physical law with experimental measurements of the same quantity; (5) to introduce the concept of measurement error and to discuss sources of uncertainty in pressure and temperature measurements; and (6) to use the Ideal Gas Law to compute the amount of gas that would need to be added or removed from a fixed volume of gas, held at constant temperature, to achieve a given increase or decrease in pressure.

This learning video explores the mysterious physics behind boomerangs and other rapidly spinning objects. Students will get to make and throw their own boomerangs between video segments! A key idea presented is how torque causes the precession of angular momentum. One class period is required to complete this learning video, and the optimal prerequisites are a familiarity with forces, Newton's laws, vectors and time derivatives. Each student would need the following materials for boomerang construction: cardboard (roughly the size of a postcard), ruler, pencil/pen, scissors, protractor, and a stapler.

This video lesson has the goal of introducing students to galaxies as large collections of gravitationally bound stars. It explores the amount of matter needed for a star to remain bound and then brings in the idea of Dark Matter, a new kind of matter that does not interact with light. It is best if students have had some high school level mechanics, ideally Newton's laws, orbital motion and centripetal force. The teacher guide segment has a derivation of centripetal acceleration. This lesson should be mostly accessible to students with no physics background. The video portion of this lesson runs about 30 minutes, and the questions and demonstrations will give a total activity time of about an hour if the materials are all at hand and the students work quickly. However, 1 1/2 hours is a more comfortable amount of time. There are several demonstrations that can be carried out using string, ten or so balls of a few inches in diameter, a stopwatch or clock with a sweep second hand and some tape. The demonstrations are best done outside, but can also be carried out in a gymnasium or other large room. If the materials or space are not available, there are videos of the demonstrations in the module and these may be used.

This learning video describes within an action orientation certain often difficult-to-understand concepts of Newtonian physics. The conservation of momentum is extended to rotational situations, and some of the results may be counter-intuitive! As Professor Lewin states in the opening segment, the prerequisite necessary for this lesson includes familiarity with the concepts of torque, angular velocity, angular momentum and moment of inertia. This interactive video lesson can easily be completed within a 55-minute class period, and the only material required is a blackboard/whiteboard to write on. During the breaks between video segments, students will be asked to think about and discuss: conditions under which angular momentum is either conserved or not conserved; examples in which the moment of inertia changes; a human ice skater and a rough estimation of her moment of inertia; as well as other topics.
