Through four lessons and four hands-on associated activities, this unit provides a way to teach the overarching concept of energy as it relates to both kinetic and potential energy. Within these topics, students are exposed to gravitational potential, spring potential, the Carnot engine, temperature scales and simple magnets. During the module, students apply these scientific concepts to solve the following engineering challenge: "The rising price of gasoline has many effects on the US economy and the environment. You have been contracted by an engineering firm to help design a physical energy storage system for a new hybrid vehicle for Nissan. How would you go about solving this problem? What information would you consider to be important to know? You will create a small prototype of your design idea and make a sales pitch to Nissan at the end of the unit." This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics. Less

Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down and eventually come to a stop. By severely limiting friction through the use of the hover pucks, students learn that the energy of one moving puck is transferred directly to another puck at rest when they collide. Students learn the concept of the conservation of energy via a "collision," and will realize that with friction, energy is converted primarily to heat to slow and stop an object in motion. In the associated activity, "The Puck Stops Here," students will investigate the frictional force of an object when different materials are placed between the object and the ground. This understanding will be used to design a new hockey puck for the National Hockey League. Less

Students investigate potential energy held within springs (elastic potential energy) as part of the Research and Revise step. Class begins with a video of spring shoes or bungee jumping. Then students move on into notes and problems as a group. A few questions are given as homework. The Test Your Mettle section concludes. The lesson includes a dry lab that involves pogo sticks to solidify the concepts of spring potential energy, kinetic energy and gravitational energy, as well as conservation of energy. Less

In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pendulum. Less

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when something heavy falls from a long distance changing its potential energy into kinetic energy. Automotive engineers need to know what happens when cars crash into each other, and why they can do so much damage, even at low speeds! Our knowledge of mechanical energy is used to help design things like bridges, engines, cars, tools, parachutes, and even buildings! In this lesson, students will learn how the conservation of energy applies to impact situations such as a car crash or a falling object. Less

In this physics activity, learners construct a small-scale version of a classic carnival game. A large marble is rolled along a track made from a commonly available and inexpensive metal shelf bracket. The track is gently bent so that there is a flat portion, then a small hill, and finally a steep uphill portion. The objective is to roll the ball so that it goes over the first hill, but does not come back over the hill -- the ball should remain in the dip between the two hills. The process involves nice illustrations of the interplay of kinetic energy, potential energy and friction. Less

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude. Less

Introduction to classical mechanics (see description under 8.01). Material is covered over a longer interval, so that the subject is completed by the end of the Independent Activities Period. During the first month of classes, substantial emphasis is given to reviewing and strengthening pre-calculus mathematics, basic physics concepts, and problem-solving skills. Delay in the use of calculus permits students more exposure to 18.01 before the material is used in the physics. Overall content, depth, and difficulty is otherwise identical to that of 8.01. Students receive credit for 8.01 on their transcripts. Credit cannot also be received for 8.012 or 8.01X. Less

After learning about transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. In groups they are given a wooden block, different fabrics, and weights and asked to design the "best" puck. The class first needs to define what makes the "best" puck. Each group should realize that the most desirable puck will travel the furthest, thus the puck with the least amount of friction. In the context of hockey the "best" puck is the one that travels farthest and loses the least kinetic energy to friction. Students then need to apply their knowledge of friction to design a new optimal puck for the National Hockey League. The friction is the transfer from kinetic energy to heat energy. Less
