Stanford Univ/gravity Probe B/relativity Q&a

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Falling objects can be brutal if you don't protect your noodle! Scholars explore the motion of falling objects through measuring short intervals to determine if the distance traveled varies with time. Building off of this, scholars...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Ready to take your class on a journey through space and witness epic battles? A video segment portrays the true way space battles happen, complete with the way Hollywood handles the lack of gravity, even while firing missiles at the...

What goes up must come down, but there is more to the phenomenon than meets the eye! As it turns out, any two objects attract to each other. The formula for Newton's law of universal gravitation is introduced in the explanation. A touch...

Students perform inquiry in response to the question "Do objects fall at the same rate?", teacher candidates discuss a model experiment for secondary students to discover the answer, including recording and analyzing data.

NASA has announced the results of an epic physics experiment that confirms the reality of a space-time vortex around our planet. [2:48]

NASA's Gravity Probe-B mission confirms two major predictions of the general theory of relativity.
