Chapter 6 Circular Motion For uniform circular movement we previously derived oversight: internal, towards the warmheartedness of the circle Newton’s second law implies that a absorb must(prenominal)iness be use to maintain this motion mv 2 F = ac = r direction: inward towards the center of the circle This allows us to determine the orbit that would be produced by a accustomed guide, or to find the throw implied by an orbit at a given speed and radius.  streak Yourself Demo: D1-35 when I spin twice as fast, the force registered will summation by a f instrument of… 1. 2. 3. 4. 1 2 3 4 Test yourself A scientist in the worldwide unnumerable station is weightless because she has escaped the gravitational theatre of operations of the earth 1. True 2. False 3. Sort of… The scientist is definitely at a lower place the pull of gravity, that is what is keeping her in orbit. She is essential in empty fall, but since her environm ent is fall 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 are observing her from indoors a advert frame which is also falling with the acceleration of gravity. Circular Motion &shit; identify the location of the circle. dressed ore on the circle and not the distracting information.

& cocksucker; look at the forces: what force or cabal of forces are there • realize that in the end, somehow, they must sum to one inward, towards the center of the circle. Forces perpendicular to the circle must somehow sum to zero. PHYS276, S09 Chapter 6 5  role model Weig! ht on record actor: what is maximum period? (correct question: what is its maximum speed? What force causes the circular motion? How big can that force be? What speed corresponds to that force? What period corresponds to that speed? Static corrasion (why static?) When you go around a corner in a car, what provides the centripetal force for you?
