OBJECTS IN FREE-FALLDef:An object in free-fall is any object that is moving freely under the influence of gravity alone, regardless of its initial position and velocity. 29.8 /msgAcceleration of Gravity Near Earth’sSurface The direction of ‘g’ is toward center of earth. Small variations of ‘g’ due to: 1. altitude 2. latitude (g is smaller at equator) 3. local earth density Since an object in free-fall moves with constant acceleration near earth, we may
