Unformatted text preview: 16 Chapt. 2 One-Dimensional Kinematics are, respectively, the 1-dimensional definitions of average velocity, velocity, , acceleration. a) average deceleration b) deceleration c) average acceleration d) speed e) average speed 002 qmult 00142 1 1 2 easy memory: average velocity sensible 15. There are different ways of defining average quantities. But one wants definitions that are useful. For example, the conventional definition for average velocity is v avg = Δ x Δ t , where Δ x is the displacement that occurred in time Δ t . This definition is USEFUL since v avg Δ t is: a) a random number. b) the displacement that takes place in time Δ t . c) a quantity with the dimension of length. d) a quantity with the dimension of velocity. e) a time. 002 qmult 00150 1 1 2 easy memory: motion diagrams 16. Graphs of kinematic variables (i.e., displacement, velocity, acceleration, jerk) versus time can all be called: a) emotion diagrams. b) motion diagrams. c) velocity diagrams....
