This educational video covers the key concepts of work, energy, and power. You’ll learn how to calculate work done from force and displacement, determine gravitational potential energy at a height, and find power in watts. We explain kinetic and potential energy differences, identify various energy types, and discuss energy transformations. Finally, we highlight the law of conservation of energy. The following are the learning objectives: (1) Explain work, energy and power and give example of each (2) Calculate : – The work done, given a force and displacement it produces in its direction, – The gravitational potential energy at height H above a given reference plane. (3) Calculate power in watts given an applied force and time it takes to produce displacement (4) Identify the types of energy possessed by a body under given condition (5) Distinguish between kinetic and potential energy (6) Identify energy transformation from one form to another. (7) state the law of conservation of energy
