Final answer:
Einstein viewed gravity as the warping of spacetime, while Newton described it as a force between objects.
Step-by-step explanation:
Einstein's view of gravity, as described in his theory of general relativity, is that mass warps spacetime, causing objects to move along curved paths. On the other hand, Newton's law of universal gravitation describes gravity as a force between two massive objects. One similarity between Newton and Einstein is that they both developed explanations for the observed motions of objects in the presence of gravity. However, their explanations differ in terms of the underlying concepts. Newton's theory relies on the concept of a force, whereas Einstein's theory focuses on the concept of the bending of space-time. An example of a difference between the two theories is how they predict the motion of objects near very massive bodies. Newton's theory predicts that objects will follow elliptical or other conic sections, while Einstein's theory predicts that objects will follow curved paths that are influenced by the warping of space-time.
