Energy Unit Assessment
30 Multiple Choice Questions — Energy, Heat Transfer, and Circuits
Learning Objectives
Define energy and identify the joule as its standard scientific unit.
Distinguish kinetic energy from potential energy and identify everyday examples of each.
State the law of conservation of energy and apply it to real situations.
Identify common forms of energy (chemical, sound, light, thermal) and describe their basic properties.
Describe and identify examples of energy transformations between different forms.
Distinguish among conduction, convection, and radiation as methods of heat transfer and identify examples of each.
Explain the effect of thermal energy on particle motion and density.
Distinguish electrical conductors from insulators and explain how each is used in technology.
Identify the parts of a simple electrical circuit and explain why current requires a complete loop.
Instructions
~2 minutes<p>This assessment covers the entire <strong>Energy</strong> unit. It draws together what we have learned about <em>kinetic and potential energy, different forms of energy, energy transformations, the three methods of heat transfer, conductors and insulators, and simple electrical circuits</em>.</p><p>There are <strong>30 multiple choice questions</strong>, each worth 1 point for a total of 30 points. Read each question carefully and select the single best answer.</p>
<ul><li>Read every option before choosing your answer.</li><li>If you are unsure, eliminate the answers you know are wrong first.</li><li>Watch for words like <strong>NOT</strong> and <strong>BEST</strong> — they change what the question is asking.</li><li>Take your time. There is no bonus for finishing early.</li></ul>
