1. "An object is in "free fall" when the only force acting upon it is gravity". 2. Is gravity in this case singular or plural? Is the acting gravity the resultant force of all bodies in the universe? 3. In theory, my own bodys gravitational force is acting on the object and thus it's not acually a free fall. My teacher just says "no, read the definition of "free fall" in the textbook". But it's in swedish and gravity is written like "the gravity", like it's a single force.
