Gravity

Between the pull of gravity and the push of air pressure, it's a wonder animals can balance or move at all. With a hands-on lesson about the center of gravity, learners discuss their own experiences with the topic, then work with...

A phenomenal lesson on potential and kinetic energy is here for your young scientists. Using a roller coaster ride, learners investigate potential and kinetic forms of energy. Additionally, everyone gets to design, construct, and try out...

Students investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air...

How do you describe gravity? Physics scholars watch as the narrator asks passers-by to try their hand at summing up a common force. The amusing answers focus on attraction and mass.

Does space have its own gravity? And, if so, why do astronauts just float around in the space station? Science sleuths examine the forces acting upon astronauts in the International Space Station with help from the narrator. He...

Gravity impacts the way you throw a ball and the way the Haumea travels around the sun. The video introduces gravity as a force. It describes the various types of orbits, escape velocity, and weightless mass. 

Sir Isaac Newton was the first person to recognize the concept of gravity. Here is a video that introduces learners to "think of gravity like the invisible super glue that holds our massive world together."

Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Students calculate effects of gravitational force on planets, discuss the effects of weightlessness on the human body and describe and demonstrate how objects in a state of free fall are accelerated by gravity at an equal rate.

Students work with boxes and weights to find the center of gravity. For this simple center of gravity experiment, students find success in using weights to move the center of gravity. Students will be assessed at the end of the lesson as...
