| Physics of Free Fall | Free fall refers to the motion of objects influenced only by gravity. The acceleration due to gravity, g, is different for different planets and at different heights above the planet. For motion near the Earth's surface (between sea level and the top of Mount Everest) g = 9.8 m/s2. (Related search term: free falling body problems; freefalling) |
