Info

Program Overview Thrilling Experiments: Potential and Kinetic Energy focuses on energy and its uses. The information presented by the narrator includes types of energy and forms of mechanical energy. Hands-on experiments are presented that demonstrate practical application of energy in mechanical and other applications. Appropriate photos, graphics and illustrations enhance each experiment as well as live action demonstrations. Viewing Objectives After viewing the DVD/video and utilizing the activities provided in the Teacher’s Guide, students will be able to: 6 • Understand and define key vocabulary words related to energy. • Solve problems involving angular motion. • Define, describe, and investigate forces in static and dynamic situations. • State and explain Newton’s Law of Gravitation. • Describe the relationship between work and energy using narrative and mathematical descriptions. • Apply the Law of Conservation of Energy to describe conceptually the conversions between potential and kinetic energy. • Describe the relationship between momentum and impulse using narrative and mathematical descriptions.

Energy Fast Facts Fast Facts • Energy is the ability to do work. • Work involves movement. • Any object with energy that moves is working. • There are five types of energy: mechanical, heat, chemical, electromagnetic, and nuclear. • Einstein was one of the first scientists to work with energy. • E=mc 2 energy is equal to mass times the speed of light squared. • The law of conservation of energy states that energy can be changed from one form to another, but cannot be created or destroyed. • Joules are units of energy. • Newton-Meters are units of work. • 1 Joule is equal to the work done when the force of 1 Newton produces 1 meter of displacement. • Two forms of mechanical energy are potential and kinetic. • Potential energy is stored energy. • Kinetic energy is energy in motion. • Potential energy is converted into kinetic energy when the object begins to move, or work. • Everything has potential energy stored in it. • KE=.5 x mass x velocity 2 • Mass = object’s volume times density • Velocity = distance object travels/time • Velocity = distance (d) divided by time (t) • PE = m x g x h • PE = mass times gravity times height • A pendulum can illustrate the law of conservation. © Sunburst Visual Media, a division of Global Video, LLC Thrilling Experiments: Potential and Kinetic Energy 7
