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. (05:53)

Gravitational force is the constant force of attraction between the masses of two objects. The attraction between all objects and the Earth is called gravity. Weight is caused by gravity: it is the measurement of gravity's force (or pull) on an obj...ect's mass. Learn more about gravity with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.

We'll learn about why we don't fly off into space, what mass has to do with it, how does air resistance work, and why gravity is different on the moon. In this compilation, Sabrina helps us understand some of these things. (14:32)

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)

In 1907, a young Albert Einstein was looking for a way to extend his special theory of relativity to include acceleration. It took him eight years to come up with general theory of relativity. This excellent video introduces the student to Einstein'...s theory in a very accessible and visual way. (03:12)

Professor Lewin of MIT gives a lecture on perceived gravity. He emphasizes the difference between weight and mass. During the lecture he looks at several scenarios where weight changes, such as a person standing on a bathroom scale in an elevator. Le...win goes as far as jumping off of his desk while holding a water jug in his hand to show the weightlessness of the water jug in free fall. He then drops a home-made bathroom scale to demonstrate weightlessness during free fall. The lecture ends with Lewin showing his students a video of astronauts training for a zero gravity environment in an airplane (50:01).

Its time for a no-holds barred match to see who was right Aristotle or Galileo as we answer the question.. Do heavier objects fall faster than lighter objects? And, of course, what Mr. O video would be complete without something just plain ridiculous... like say dropping water balloons off a 20+ foot balcony. (Yes, it was fun, but dont try it at home kiddies!). (05:31)
