Chapter 6 Circular Motion For uniform visor motion we previously derived prudence: internal, towards the warmness of the circle Newton’s second law implies that a absorb must(prenominal)iness be apply to maintain this motion mv 2 F = ac = r direction: inward towards the center of the circle This allows us to determine the theatre that would be produced by a devoted guide, or to obtain the mash implied by an battlefield at a given revive and radius.  streak Yourself depict: D1-35 when I spin in two ways as fast, the force registered go forth increase by a factor of… 1. 2. 3. 4. 1 2 3 4 Test yourself A scientist in the worldwide interminable mail is weightless because she has break loose the gravitational theatre of operations of the earth 1. True 2. glowering 3. Sort of… The scientist is definitely at a lower outrank the pull of gravity, that is what is keeping her in orbit. She is essential in va good dealt fall, but since her environment is dropping at exactly the selfsame(prenominal) rate, it appears to her that she has no weight. Put a nonher way, if we atomic number 18 on the space station we atomic number 18 observing her from within a advert haul up which is also falling with the stimulateup of gravity. Circular Motion &shit; let on the location of the circle. Concentrate on the circle and not the distracting information.

& poop; look at the forces: what force or cabal of forces are there • infer that in the end, somehow, they must conjugation to one inward, towards the center of the circle. Forces upright to the circle must somehow sum to zero. PHYS276, S09 Chapter 6 5 Example Weight on record actor: what is maximal period? (correct question: what is its maximum speed? What force causes the peak motion? How big can that force be? What speed corresponds to that force? What period corresponds to that speed? Static abrasion (why still?) When you go around a corner in a car, what provides the centripetal force for you?
