Exempel på hur man kan använda KINEMATICS i en mening

• The branch of physics describing the motion of objects without reference to their cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics.
• In kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a non-negative scalar quantity.
• Forward kinematics, in robotics and animation, the use of kinematic equations to find the position of an articulated object.
• Some physics programmers may even delve into the difficult tasks of inverse kinematics and other motions attributed to game characters, but increasingly these motions are assigned via motion capture libraries so as not to overload the CPU with complex calculations.
• Some scientific subfields used by engineers include thermodynamics, heat transfer, fluid mechanics, statics, dynamics, mechanics of materials, kinematics, electromagnetism, materials science, earth sciences, and engineering physics.
• The dynamics of a rigid body system is described by the laws of kinematics and by the application of Newton's second law (kinetics) or their derivative form, Lagrangian mechanics.
• In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.
• The brain uses information from the vestibular system in the head, and from proprioception throughout the body to enable an understanding of the body's dynamics and kinematics (including its position and acceleration) from moment to moment.
• Mayor's research interests include extrasolar planets (also known as exoplanets), instrumentation, statistical properties of double stars, globular cluster dynamics, galactic structure and kinematics.
• This article, "Foundations and goals of analytical kinematics" develops the field of kinematics, in particular exhibiting an element of E(3) as a homography of dual quaternions.
• Sales weren't helped when the MPV received one star out of four in the Australian Australasian New Car Assessment Program (ANCAP) crash tests and a "Marginal" rating in the American Insurance Institute for Highway Safety (IIHS) crash tests for damage to the occupant compartment, tire intrusion into the driver footwell area, poor dummy kinematics, and possibility of injuries to both legs.
• An alternative approach is to ignore the kinematic term and read odometry data from robot wheels after each command—such data may then be treated as one of the sensors rather than as kinematics.
• Inverse kinematics post-processing: used in , this technique relies on playing a pre-set death animation and then using inverse kinematics to force the character into a possible position after the animation has completed.
• Later, the vortex sheet detaches from the feeding jet and propagates freely downstream due to its self-induced kinematics.
• From a kinematics point of view, given a plane curve, called the directrix, a cylindrical surface is that surface traced out by a line, called the generatrix, not in the plane of the directrix, moving parallel to itself and always passing through the directrix.
• The flywheels are then controlled by the SCAO which tries to follow a selection of the brightest stars in order to ensure the desired kinematics.
• Robot kinematics studies the relationship between the dimensions and connectivity of kinematic chains and the position, velocity and acceleration of each of the links in the robotic system, in order to plan and control movement and to compute actuator forces and torques.
• William Kingdon Clifford initiated the use of dual quaternions for kinematics, followed by Aleksandr Kotelnikov, Eduard Study (Geometrie der Dynamen), and Wilhelm Blaschke.
• Combining data from both manual and virtual palpation protocols allows achieving supplementary analysis: registration protocols aiming at building reference frames for motion representation according reproducible clinical conventions; to modelize joint kinematics accurately during musculoskeletal analysis; to align precisely orthopedic tools according to the individual anatomy of a patient; or to wrap and to scale surface textures to motion data when creating animation characters.
• A little later in the same year Albert Einstein published his original paper on special relativity in which, again based on the relativity principle, he independently derived and radically reinterpreted the Lorentz transformations by changing the fundamental definitions of space and time intervals, while abandoning the absolute simultaneity of Galilean kinematics, thus avoiding the need for any reference to a luminiferous aether in classical electrodynamics.
