[Free Registration/Login may be required to access all resource tools.] Function transformations combining shifts, reflections, stretches and compressions.

In the following interactive students will define conservative force, potential energy, and mechanical energy. They will explain the potential energy of a spring in terms of its compression when Hooke's Law applies. Students will also...

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

Through a five-lesson series that includes numerous hands-on activities, students are introduced to the importance and pervasiveness of bridges for connecting people to resources, places and other people, with references to many...

By the end of this section, you will be able to define conservative force, potential energy, and mechanical energy; explain the potential energy of a spring in terms of its compression when Hooke's law applies; and use the work-energy...

[Free Registration/Login may be required to access all resource tools.] The following online tutorial describes how a gas can be compressed and identifies three factors that affect gas pressure. Students will describe the effects...
