Text: Near the surface of the earth gravity is a downward acceleration. Over time, it causes all unsupported objects to pick up a downward speed. Since gravity is a persistent acceleration, falling objects keep falling faster and faster. For objects near the surface of the earth, gravity causes them to accelerate downward at a constant 9.81 meters (m/sec)/sec. This means each second it falls, it will be traveling 9.81 meters per second faster.
