Unformatted text preview: 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...
