Suppose that an object with a mass of one kilogram and an object with a mass of two kilo the Earth's surface. As compared to the one kilogram object, the two kilogram object accelerates grams are both in free fall near O A more because gravity pulls on it more strongly. O B less because it has more inertia. O Cthe same because gravity pulls on it more strongly and it has more inertia. O D more because gravity pulls...
