This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
a) The work done by gravity when the object reaches 5 m height. b) The work done by gravity when the object comes back to Earth. c) Total work done by gravity both in upward and downward motion and mention the physical significance of the result. Solution
Follow along with common work and power example problems and solutions. See how to solve problems when force is applied directly parallel or at an angle.
A collection of exercises on work and energy, complete with solutions, to help you in your study of these central topics in dynamics!
Work is done whenever a force causes a displacement. When work is done, energy is transferred or transformed. The joule is the unit for both work and energy.
How much work do you do to move the child from \(\theta=0\) to \(\theta=\theta_1\)? Use a detailed diagram to show that the work done by \(\vec F\) is equal to \(mgh\), where \(h\) is the change in height of the child.
