The description of right lines and circles, upon which geometry is founded, belongs to mechanics. "Kine" is Greek for move, "ma" for thing and the suffix "-tic" from the verb "tikto" ;to create , so create thing to move becomes kinematic.There is no mention of how much power is used which may be minimal, as in a mobile `phone ( kinetos telephonos?) Describe a system. One way to think about the difference between kinematics and dynamics is that dynamics is the cause of motion and kinematics is the effect. Anonymous comment on How does the income approach to measuring GDP differ from the expenditure approach? Perfect prep for Review of Kinematics quizzes and tests you might have in school. This is where forces and equations of motion come in. what kind of physical quanity is a force. Some were proven false, while others have grown to be the basis of entire fields of study. and utilizing different tools to analyze these objects. Kinematics and dynamics are branches of mechanics, which is the study of forces and motion in physics. We need you to answer this question! They include under dynamics both kinetics and kinematics (the description of motion in terms of position, velocity, and acceleration, apart from the influence of forces, torques, and masses). a. K describes matter and D tells what it does. As nouns the difference between dynamics and kinematics is that dynamics is (mechanics) the branch of mechanics that is concerned with the effects of forces on the motion of objects while kinematics is (physics) the branch of mechanics concerned with objects in motion, but not with the forces involved. This shift in emphasis is important, since it entails dealing with complex objects . Kinematics describe the motion of an object without considering the forces that cause the motion. Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions). Kinematics vs Dynamics • Both dynamics and kinematics are study of motion but whereas causal forces are taken into account in dynamics there is no regard to such forces of interaction in kinematics. This is reported using centistokes. Dynamic viscosity (also known as absolute viscosity) is the measurement of the fluid’s internal resistance to flow while kinematic viscosity refers to the ratio of dynamic viscosity to density. Dynamic viscosity is symbolized by either ‘µ’ or ‘n’, while Kinematic viscosity is mathematically symbolized by ‘v’. b. K describes motion and D describes matter. However, kinematics is a useful study that has helped in many applications such as robotics, space science etc. It is not known whether the kinematic primitives for voluntary movements are represented in spinal cord. Kinetics is focused on understanding the cause of different types of motions of an object such as rotational motion in which the object experiences force or torque. Give an example that illustrates the difference between these two quantities. Dynamics is the study of motion, along with the factors that cause motion. Does a car’s odometer measure position or displacement? Key Terms. b. K describes motion and D describes matter. What makes kinematic viscosity differ from dynamic ? 2.1K views Kinematic viscosity incorporates fluid density as part of its measurement. In dynamics, we would also consider the causes of motion. As a noun dynamic is a characteristic or manner of an interaction; a behavior. Normal individuals learn to ‘coarticulate’ primitive submovements into new compound kinematic ‘primitives’ through adaptation.
