We explored the force of "Gravity" in our Science Assembly today. We talked about how objects fall at the same rate regardless of their weight and size. Ms Hollowbread demonstrated this by dropping two water bottles (one full and one empty). They hit the floor at the same time! We tried the same experiment with paper (one piece flat and one piece scrunched up). The scrunched up piece hit the floor first. The factor that makes a difference is "air resistance". In this video we saw what happens in a vacuum where the is no "air resistance".
Brian Cox visits NASA's Space Power Facility in Ohio to see what happens when a bowling ball and a feather are dropped together under the conditions of outer space.
