Newton's Laws of Motion N1L - Law of Inertia N2L - Force Law F=ma N3L - Law of Action and Reaction NULG Let two objects in space, one large, the other small, be at rest some distance from each other. What will happen? N1L - They will not change their state of motion (rest) without a force NULG - both have mass so they exert a force on each other N3L - These forces are equal and opposite N2L - The force produces a large acceleration on the small body and a small acceleration on the big body. An observer sees the small body fall onto the large body (the large body falls upwards only marginally before they collide). Let the same two objects now pass some distance from each other in space, moving with a relative speed v. What happens? N1L - They will not change their state of motion without a force

Unformatted text preview: NULG - both have mass so they exert a forces on each other N3L - These forces are equal and opposite N2L - The force produces a large acceleration on the small body and a small acceleration on the big body. An observer sees the small body fall towards the large body (the large body falls upwards only marginally). If the initial speed v was small and the closest separation was small, the observer sees the small body fall down onto the large body. If the speed v and/or initial separation r was large enough, he sees the smaller body begin to orbit the larger body. If the speed v was even larger he sees the small body deflected from its path but not captured (the larger body is also deflected, but not by much)....
