This is the portal for a collection of short videos that explore the science behind professional hockey. Funded by the National Science Foundation, the videos aim to provide engaging real-world examples of key concepts in physics: Newton's Laws, momentum and its conservation, conservation of energy, vectors, impulse and collision, and projectile motion. NHL players are featured in each video, with motion displayed in archived game clips and newly-created video captured with a super high-speed Phantom Cam. Physicists appear in each video to explain the concepts being demonstrated and clarify the connections to physics. Included are 20 lesson plans for middle school and high school, developed for use specifically with the videos.
6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
9-12: 4E/H9. Many forms of energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on the separation between mutually attracting or repelling objects.
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.
