19. Some people have the wrong idea that there is a force that tends to push the circling object outward in a radial direction. They call this force 20. The proof that there is no force radially pulling the object is the tangential direction taken when the centripetal force is removed. If centrifugal force exists then the object would travel in a 21. This does not happen. When there is relative motion between an object and water or a gas, friction happens due to 22. All machines, no matter how complicated, can be dissected to their simplest components: the 23. and Work is defined as the application of force on a system or an object, which causes the latter to move along a certain
