Learn how to solve problems of work and energy using the basic equation and the law of conservation of energy. See examples of problems with solutions and diagrams for different situations.
This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
In this collection of exercises we will study the concepts of work and energy and see how these quantities manifest themselves and interconnect, including through familiar objects from previous collections such as springs and inclined planes.
In the analysis we found that the work done by friction over path #2 is greater than the work done by friction over path #1 by a factor of \(\frac{\pi}{2}\). From the work-energy theorem, this means that the changes in kinetic energy for these two paths are related in the same way:
We can again use the Work-Energy Theorem to determine the work done by friction as the skier slides up the ramp. We know that the speed of the skier at the bottom of the ramp is \(v_i\), and we just found that the speed of the skier at the top of the ramp is \(v_t=\sqrt{v_f^2-2gh}\).
