Describe what is meant by work done, How to calculate work done by a force moving an object, How work done is a form of energy transfer, examples and step by step solutions, GCSE / IGCSE Physics, notes • What is the equation for work? • How do you use the equation to calculate the work done on an object? The Work Equation: The work done (W) depends on three variables: 1. 1. e. Aimed at lower to mid ability KS3. In our previous post, we have studied the basics concept behind the centrifugal pump. distance graph and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills. It uses formula triangles to make the content accessible for lower ability students. (3) Dr. )kinetic energy, which is considered later. Student feedback says that they love the layout. A car moving at The formula for work done is: Work done = force × distance You can rearrange this equation with the help of the formula triangle: Use the formula triangle to help you rearrange the equation. Worked Example. 2. This leaderboard is currently private. A 10 ft long trough with a cross section as a triangle with a base of 3 feet, and a height of 3 feet, is full of water.
