Version 2 is now LIVE! We have more than tripled the number of problems, broken each unit into several smaller, single-topic problem sets, and utilized a random number generator to provide numerical information for each problem. Student answers are automatically evaluated and feedback is instant.
Use work and energy principles to calculate a speed or a height or an energy value. Most problems include little to no little scaffolding. Includes 10 problems.
The problems below are provided as additional problems to the original set of 32 Work and Energy problems. Just like problems in the original set, these problems consist of a problem, an answer (revealed by clicking a link), an audio guided solution, and links to an Overview page of formulas and to The Physics Classroom Tutorial pages.
Here is available the collection of exercises solved on energy and work, physical quantities central to dynamics and of great importance in all branches of modern physics. Thanks to these we are able to describe how the world around us moves, transforms, and how its elements interact with each other.
This example shows how we can start to think about energy as something that is "conserved'', which we will explore in more detail in the next chapter.
This unit is part of the Physics library. Browse videos, articles, and exercises by topic.
The potential energy of world class pole vaulters now routinely exceeds the kinetic energy of world class sprinters. It would appear that vaulters have discovered a way to "violate" the law of conservation of energy.
