Energy can be quantified as amount of work that can be done by a force. There are many forms of energy such as kinetic, potential, thermal, gravitational, sound, light, electromagnetic, chemical and nuclear energy. Energy can be changed from one form to another, but total energy in an isolated system remains constant, it can neither be created nor destroyed.

Presentations on Energy and Work : |

Work, Force, Energy and MotionGrade: 5 - 12 In this lesson learn how to calculate the force, energy, motion and work of an object. Find out how these properties compare with one other. The lesson also explains the difference between potential and kinetic energy as well as how to calculate gravitational potential energy with help of examples. 8:50 |

Work and Energy, part 1Grade: 8 - 12 Introduction to the concepts of - work and energy. 9:15 |

Work and Energy, part 2Grade: 8 - 12 Introduction to kinetic energy and potential energy. 9:50 |

What is Work?Grade: 5 - 12 The lesson demonstrates the relationship between work, force and distance. An example problem illustrates how to calculate work. 2:15 |

Energy and WorkGrade: 5 - 12 Learn about the relationship between energy and work. The lesson explores ways people try to overcome Earth's gravity in order to do work. 2:30 |

Lesson - InertiaGrade: 5 - 12 The lesson introduces the concept of inertia, the first law of physics - Things like to keep on doing what they're already doing. 4:50 |

Lesson - MassGrade: 5 - 12 Building on the idea of inertia, this lesson introduces the concept of mass, tells how it's measured, and shows how it differs from size. It explains that inertia increases with mass. 4:50 |

Lesson - SpeedGrade: 5 - 12 The lesson introduces the concept of speed to the inertia-mass relationship. It explains that force varies with mass and rate of change of speed. 4:50 |

Lesson - Acceleration, part 1Grade: 5 - 12 Learn about the concept: Force = mass x acceleration. The lesson illustrates this important rule of physics with the examples of a bicycle and a baseball player. 4:50 |

Lesson - Acceleration, part 2Grade: 5 - 12 The lesson explains how acceleration works, and how to calculate it with the help of an animated locomotive. It stresses the importance of reasonable units, and that acceleration is measured in m/s². 4:50 |

Lesson - GravityGrade: 5 - 12 The video explains the force of gravity with the help of Isaac Newton's celebrated falling apple. It also explains the unit with which the force of gravity is measured. 4:50 |

Lesson - Weight vs. MassGrade: 5 - 12 Learn about the difference between mass and weight, and understand how only mass of an object is the same on the moon and on the earth, but not its weight. 4:50 |

Lesson - WorkGrade: 5 - 12 Understand the concept that Work = Force x Distance. In the lesson, a circus troupe helps present the physics definition of work. 4:55 |

Lesson - Kinetic EnergyGrade: 5 - 12 Learn about kinetic energy - the energy of motion. Animated billiard balls help demonstrate kinetic energy. 4:50 |

Lesson - Potential EnergyGrade: 5 - 12 Learn about potential energy, which is the energy of position. A rock teetering on the edge of a cliff is demonstrated to have potential energy. 4:50 |

Introduction to FrictionGrade: 5 - 12 Lesson on force of friction. Force of friction can be classified as static or kinetic force of friction depending on whether the body is at rest or in motion. It explains that the frictional force is directly proportional to the weight of the body. 7:00 |

Conservation of EnergyGrade: 8 - 12 Using the law of conservation of energy, the lesson explains how potential energy is converted into kinetic energy. 10:05 |

Work and Energy problem with FrictionGrade: 8 - 12 A conservation of energy problem where it seems all of the energy is not conserved. 10:05 |

Introduction to MomentumGrade: 8 - 12 The lesson explains what momentum is. It illustrates a simple problem involving momentum. 9:15 |
