Gravitational force is the constant force of attraction between the masses of two objects. The attraction between objects and the Earth is called gravity. Weight is caused by gravity: it is the measurement of gravity's force on an object's mass. L...earn more about gravity and inertia with this cartoon animation from StudyJams. A short, self-checking quiz is also provided with this link.

This humorous video shows examples to help explain the differences between the theories of gravity provided by Aristotle and Galileo. After the first experiment have the students reach a conclusion about which scientist was right. Let the video play ...to the end and see which students were correct. A good lesson.

La gravedad es la fuerza más poderosa y precisa del Universo, que todo lo domina y atraviesa. La fuerza de la gravedad nos mantiene unidos, sostiene a las estrellas en el cielo y aplasta la luz. La gravedad también mantiene a los planetas unidos y ha...ce que orbiten alrededor de sus soles. Sin la gravedad, las estrellas, los cometas,
las lunas, las nebulosas e, incluso, la propia Tierra, no existirían.

Einstein predicted gravity waves in his general theory of relativity, but to date these ripples in the fabric of space-time have never been observed. Now a scientific research technique called Atomic Interferometry is trying to re-write the canon. In... conjunction with researchers at Stanford University, scientists at NASA Goddard are developing a system to measure the faint gravitational vibrations generated by movement of massive objects in the universe. The scientific payoff could be important, helping better clarify key issues in our understanding of cosmology. But application payoff could be substantial, too, with the potential to develop profound advances in fields like geolocation and timekeeping. In this video we examine how the system would work, and the scientific underpinnings of the research effort. (02:31)
