TED-Ed: How to think about gravity - Jon Bergmann

The video tutorial explains the concept of gravity, starting with the common misconception that what goes up must come down. It introduces the law of gravity as an equation and explains that all objects with mass are attracted to each other. Through examples like a rock falling off a cliff and analogies with magnets, the video illustrates how gravity works. It discusses the role of mass and distance in gravitational attraction, using examples like astronauts on the moon and the sun's influence on Earth. The tutorial concludes by highlighting the mystery of gravity's cause, which remains unknown to scientists.

Why do astronauts weigh less on the moon compared to Earth?
