Unformatted text preview: MECHANICS KINEMATICS Kinematics is the study of motion, without the investigation of the cause for the motion OTION otion of what? Material point (An object with an irrelevant dimension for the purposes of a particular problem) Development of models Example: linear movement v. rotation Motion is relative to the object of reference Examples: the motion of an airplane passenger relative to the air plane, or the motion of an air plane passenger relative to the ground. System of reference: The object of reference System of coordinates (measures distance) Watch (measures time) y x z 1 r r 2 r 1 2 1 2 t r t r r r r ONE DYMENTIONAL (1D) UNIFORM MOTION (Motion along a straight line with a constant velocity) x 0 x 1 x 2 t x x 1 1 t x x 2 2 t x x 1 2 x x x 1 2 1 2 then if x x t t v t x t x 2 2 1 1 Uniform - motion with a constant ratio:...
