40 Chapt. 4 Two- and Three-Dimensional Kinematics a) continually changing too. b) continually changing and constant, respectively. c) constant and continually changing, respectively. d) constant and undefined, respectively. e) both constant. 004 qmult 01020 1 1 1 easy memory: non-uniform motion acceleration 31. In circular motion, an object is moving in a circle about some center. The acceleration of an object continuously in NON-UNIFORM circular motion: a) does NOT point directly toward the center. b) points directly toward the center. c) points directly outward from the center. d) maybe points directly toward the center. e) is zero. 004 qmult 01030 1 1 4 easy memory: radius of curvature 32. Many, but not all, sections of a smooth curved paths in a plane can be approximated to good accuracy by section of circle. The radius of the circle is called the radius of curvature. A circle is fitted to a curved path over some region by adjusting its position and orientation. In many, but not all cases, a fitted circle can be made to agree to 1st order with a curved path about some point common to both. Agreement to 1st order means that both curved path and circle can be approxiated by the same quadratic function without any linear terms in the neighborhood of the common point. The function’s argument is the coordinate of an axis which is tangent to both curves. Say one has a case where one does a fit and gets 1st order agreement. If the curved section is made straighter, the radius of curvature:

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
