Understanding why an orbiting satellite neither travels in a straight line away from the body about which it is revolving, nor falls inward toward it, is an important concept in both astronomy and physics. Demonstrating an orbit in a classroom is made difficult by the Earth's gravity. The Earth's gravity can be used, along with simple kitchenware, to create a model of a planetary or satellite orbit.
