Create an Atwood's machine and a modified Atwood's machine in this interactive. Change the amount of mass on either object, introduce friction forces, and measure distance and time in order to calculate the acceleration.

This Java applet allows the user to name any two points in a Cartesian system, see the segment on the screen and view how the distance between the two points is found.

[Free Registration/Login Required] Students explore the concept of the distance formula by navigating through the interactive learning module and then answering questions that go along with the module. Students can also learn more about...

This resource explains why data collection is a great way to make informed improvements to a design, and how to do it. Data can be quantitative - such as a measurement of distance or time - or qualitative, such as an observation of...
