<li>The net work \({W}_{\text{net}}\) is the work done by the net force acting on an object.</li>
<li>Work done on an object transfers energy to the object.</li>
<li>The translational kinetic energy of an object of mass \(m\) moving at speed \(v\) is \(\text{KE}=\frac{1}{2}{\text{mv}}^{2}\).</li>
<li>The work-energy theorem states that the net work \({W}_{\text{net}}\) on a system changes its kinetic energy, \({W}_{\text{net}}=\frac{1}{2}{\text{mv}}^{2}-\frac{1}{2}{m{v}_{0}}^{2}\).</li>

<h2>Glossary</h2>
<h3>net work</h3>
<p>work done by the net force, or vector sum of all the forces, acting on an object</p>
<h3>work-energy theorem</h3>
<p>the result, based on Newton’s laws, that the net work done on an object is equal to its change in kinetic energy</p>
<h3>kinetic energy</h3>
<p>the energy an object has by reason of its motion, equal to \(\frac{1}{2}{\text{mv}}^{2}\) for the translational (i.e., non-rotational) motion of an object of mass \(m\) moving at speed \(v\)</p>
