- Legacy Problem Set
The Work–Energy Theorem. In physics, the term work has a very specific definition. Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is described by the equation
On the following pages you will find some problems of work and energy with solutions. Try to do them before looking at the solution. Work and Energy - Work done by a constant force. Work and Energy - Work done by the weight force and potential energy.
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.
This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
Learn more about work and energy in this PhET simulation called “the ramp.” Try changing the force pushing the box and the frictional force along the incline. The work and energy plots can be examined to note the total work done and change in kinetic energy of the box.
We will determine the speed at the top of the ramp, \(v_t\), using the Work-Energy Theorem: \begin{align*} W^{net}=\frac{1}{2}mv_f^2-\frac{1}{2}mv_t^2 \end{align*} where \(W^{net}\) is the net work done on the skier as they "fly'' through the air.
