The earth has radius of 6,357,000 meters, and a mass of 5.972*1024 kilograms. An elephant has a mass of 6,000 kilograms. What would the force of gravity on the elephant, from the earth, be?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
