Here's a force to be reckoned with in the physics classroom! Scholars discover the movements associated with tension, compression, and other common forces through a hands-on simulation. Pupils pull, push, and twist their way through each...

Join together to investigate truss joints. Scholars learn how to analyze forces at truss joints to determine the strength of truss bridges. They apply the "method of joints" in calculating the tension and compression forces at each joint...

The final lesson in the 20-part series is a post assessment covering earthquakes and volcanoes. Twenty-three questions incorporate each of the previous lessons through multiple choice, justified multiple choice, expanded multiple choice,...

Invite your learners to take a closer look at the art and mathematical function of dome buildings as designed by the ancient Romans. In the next segment of this attractive activity set, your young historians will then learn about ancient...

This lesson introduces the concept of tension. It is 1 of 2 in the series titled "Introduction to Tension."

Students must solve for the tension in the rope and the acceleration of the car based on the angle of displacement for a hanging mass.
