Gravity is measured in some odd unit likmaybe grams-pressure-how but force how does it work the sicentists under stande but what about those of us that dont know how to use those calculations well its simple well lets start with how its measured. Well its measured in meters per second/ mps so to help you image this imagin youre two meters from the ground, if u walk stright off and kept your body strait till u hit the ground then it will take about 1.75 seconds till you hit the ground because you would gain one meter every second so every second you are falling your going one meter faster. Now what it does is easy but for those of you who dont know is it the force that keeps us from floating around or falling upside down so now you know how important gravity is.
