Flexi Says: All objects in the universe have an attraction to each other. This attraction is known as gravity. The strength of the force of gravity depends on two things. One is the mass of the objects. The other is the distance between the objects. As an object's mass increases, the attraction increases. As the distance between the objects increases, the attraction decreases. The acceleration is directly dependent with gravity. The increase in gravity increases the acceleration. So mass of the object will be independent variable and the gravitational acceleration will be dependent variable.
