I WONDER - How Does Gravity Work?

The video tutorial explains gravity as the force pulling objects toward each other on Earth, giving them weight and causing them to fall at an acceleration of 9.81 m/s². It describes freefall as the state when only gravity acts on an object, and notes that without air resistance, all objects fall at the same rate regardless of mass. This concept was demonstrated by astronaut David Scott on the moon, where he dropped a feather and a hammer, both hitting the surface simultaneously due to the lack of atmosphere.
