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...

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...

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 is thoroughly defined in this short, but weighty, featurette. The relationship of mass to force is incorporated, and the idea that gravity can also attract energy is introduced. In a flipped classroom situation, have learners...

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. 

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...

Most people know the famous story of Sir Issac Newton and the apple. Watch that example animated, narrated, and explained. Class members can learn what gravity is, why it pulls things down, how strong it is, and how it's related to...

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. In 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...
