Students explore the force of gravity. This video also discusses the role of gravity in the solar system. Concepts and terminology include force, gravity, attraction, orbits, and tides.

Gravity is the most powerful and exacting force in the universe. It binds us together, its reach hangs stars in the sky and its grip crushes light. Without gravity, stars, comets, moons, nebulae, and even the Earth itself would not exist. Explore how science and humanity discovered, overcame, and utilized gravity. Learn what it takes to propel objects into the heavens, to ride a wave, or to ski down a slope. Take a front row seat as an astronaut subjects himself to the weightless wonders of the specially modified aircraft used to train astronauts known as the "Vomit Comet."
Visualize the gravitational force that two mass spheres exert on each other. Move spheres in meters, change mass in kilograms, and observe changes to the gravitational forces that m1 and m2 exert on each other.

Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term gravity. Part of the Science Video Vocab Series.
Visualize the gravitational force that two objects exert on each other. Discover the factors that affect gravitational attraction, and determine how adjusting these factors will change the gravitational force.
Elevators move the equivalent of the world's population every 72 hours, but how safe are they? In this episode, experts test the strength of cables against gravitational pull with surprising results. Find out what it takes to work against the force of gravity. Part of the "Break It Down" series.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. Manuel, Gabi and Leo land in a planet where they discover that they are much stronger than on Earth. Maqui explains the difference in strength is due to the change in gravity. The kids learn about gravity throughout the universe.
Introduces caveman Zog to Newton's basic laws of motion. By observing objects on earth and in space, Zog learns that nothing can start moving, speed up, slow down, change direction, or stop unless a force is applied to it--even if the force is hard to see, like gravity or friction. He learns that for every force there is an equal and opposite force and that is the principle behind jet propulsion. And he learns that, scientifically, work occurs only when a force moves an object some distance.
Actors portray prominent scientists and astronomers as they present the history of astronomy from Plato to Newton in its historical and cultural contexts. The Greeks reasoned that the universe was geocentric--the earth was at its center. Not until Copernicus did the theory of the sun as center take root. Each major astronomer declares his different theory until Newton's answers all questions about gravitational pull between planets.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Phoebe is to participate in a slam-dunk during contest at half time of the big basketball game. The problem is Phoebe can't jump high enough. "If only gravity didn't pull on me." she moans. Never one to be tied down, Ms. Frizzle sends the class into space and turns the Bus into a planet — with adjustable gravity. The class finds basketball's a snap with low gravity and a riot with no gravity at all, but when there's way too much gravity, things get really heavy.
Gravity rules the life cycle of stars. During the Red Giant dying stage in the life of an average size star, its outer layers are blown off in vast clouds of dust and gas called "nebulae" that contain hydrogen, oxygen, and nitrogen. Gravity crushes the remaining atoms into a remnant core called a white dwarf. The gravity of giant stars-10 to 20 times larger than average-will, at the end of their life in a supernova explosion, crush together even mutually repulsive protons and electrons, leaving a remnant rotating core of neutrons (i.e., a pulsar). Also explains how stars 20 to 100 times average size collapse into a core so dense that its gravity doesn't even allow light to escape (i.e., a black hole).
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
Depicts the different stages in the birth and death of stars, including the sun. There are 100 billion stars in the Milky Way galaxy alone, and there are 100 billion galaxies. Provides an overview of radiated energy, which is in all wavelengths; nuclear fusion; and fierce magnetic fields, which create all solar events. Explains that the length of a star's life and how it dies are determined by gravity and how gravity is proportional to size.
To change a spacecraft's speed and direction, NASA engineers use a planet's or moon's gravity, a process called a "gravity assist." In this video, students design and build systems that use magnets to control the speed and direction of a rolling ball. As they build their systems, they use the engineering design process, apply a variety of science concepts, and learn how NASA spacecraft use gravity to help them explore the solar system. Part of the "Design Squad Nation" series.
Shows how gravity affects erosion. Documents how scientists study erosion and weathering. Highlights the California landslide problem. Surveys the destruction caused by fast erosion. Explains why deforestation and building houses and other structures contribute to erosion.
Part of the "Active Physics, Third Edition" series. Contains the following sections: "Using Models: Intersections with a Yellow Light," "Sports Montage Introduction," "Conservation of Energy: Defy Gravity," "Safety Montage Introduction," "Acceleration Due to Gravity: Free Fall on the Moon," and "Modeling Human Motion: Bounding on the Moon."
Students will learn about force and the effects of force on objects. Visual examples and real-life demonstrations promote an understanding of how things move. Important terminology includes force, work, friction, gravity, mass, and acceleration.
Galileo, Newton, and Einstein make appearances in this segment. Through lyrics, they explain the contributions they made to astronomy. Part of the "Space School Musical" series.
Drop balls to begin observations. Note this sim does not yet have a Keyboard Shortcuts dialog, and simple descriptions are in progress.
