Description
Welcome! I created this full-page problem and question set about potential energy for my middle school physical science students.
In part I, students complete a fill-in-the-blank section about gravitational potential energy (P.E.). In this section, students perform the following tasks.
-
Write the paralleled meaning of position and storage energy
-
Map out the equation for P.E.
-
Indicate how a change in gravity (beyond our planet) or how a change in vertical height of an object will affect P.E.
-
Write out what the "g" constant represents
-
Identify the SI unit name and its symbol for energy.
I included a word bank for the first section.
Then in part II, students solve six problems using dimensional analysis. They solve for potential energy twice, vertical height of an object twice, and for the mass of an object twice. I provided the equation for potential energy on both pages, along with a breakdown of what the variables mean. I also posted the triangle method image of the equation in the header of the first page for students who prefer using that method.
This PDF file will become editable upon conversion to Microsoft Word using an Adobe Acrobat Reader DC program.
I included a complete key with the answers in red font that show each step of the dimensional analysis. The answers also honor the multiplication and division rules for significant figures.
I appreciate your interest. This lesson correlates with my other publications about energy and work for physical science.
