"Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move."
Study of motion, without regard to the forces involved.
Position and Displacement: Position refers to the location of an object relative to a reference point, while displacement refers to the change in position of an object over time.
Speed and Velocity: Speed refers to the rate of change of position over time, while velocity includes both speed and direction.
Acceleration: Acceleration refers to the rate of change of velocity over time.
Projectile Motion: Projectile motion is the movement of an object through the air, influenced by forces such as gravity and air resistance.
Circular Motion: Circular motion is the movement of an object around a central axis or point, characterized by constant speed and changing velocity.
Force: Force is any interaction that can change the motion of an object, such as gravitational, electromagnetic, and contact forces.
Momentum: Momentum is the product of an object's mass and velocity, and it describes the tendency of an object to resist changes in its motion.
Work and Energy: Work is the product of force and displacement, while energy is the ability to do work.
Potential and Kinetic Energy: Potential energy is energy that is stored due to an object's position, while kinetic energy is energy that is due to an object's motion.
Conservation of Energy and Momentum: The principles of conservation of energy and momentum state that energy and momentum cannot be created or destroyed, only transferred or transformed.
Friction: Friction is the force that opposes motion between two surfaces in contact, and it can influence the speed and direction of an object's motion.
Center of Mass: The center of mass of an object is the point at which the object's mass is evenly distributed in all directions.
Moment of Inertia: The moment of inertia is a measure of an object's resistance to rotational motion, and it depends on both its mass and its distribution.
Torque: Torque is the rotational equivalent of force, and it describes the ability of a force to cause rotational motion.
Angular Velocity and Acceleration: Angular velocity and acceleration describe the rate of change of an object's angular position and velocity over time.
Linear Kinematics: Linear kinematics deals with the movement of objects or bodies in a straight line. It studies the displacement, velocity, and acceleration of an object in a straight line.
Angular Kinematics: Angular kinematics studies the motion of objects or bodies in circular motion. It focuses on angular displacement, angular velocity, and angular acceleration of objects in rotational or circular motion.
General Motion: General motion, as the name suggests, studies the complex motion (a combination of linear and angular motion) of objects or bodies. It is also known as curvilinear motion.
Planar Kinematics: Planar kinematics refers to the study of motion of objects or bodies in a two-dimensional plane. It considers motion along both the x and y-axes.
Three-Dimensional Kinematics: Three-dimensional (3D) kinematics encompasses the study of motion of objects or bodies in a three-dimensional space. It considers motion in all the three axes- x, y, and z.
Kinematics of Gait: Kinematics of gait is a specialized field of biomechanics that focuses on the study of movement during walking or running. It considers parameters such as gait cycle, stride length, and foot placement during walking or running.
Kinematics of Sports Movements: Kinematics of sports movements is a specialized field of biomechanics that focuses on studying the kinematics of various sports movements, such as throwing, jumping, kicking, and batting. It considers factors such as joint angles, velocity, and acceleration during the sports movements.
Kinematics of Artificial Limbs: Kinematics of artificial limbs deals with the study of motion of prosthetic limbs for people with disabilities. It looks at the design and movement of artificial limbs to mimic natural motions of human limbs.
Kinematics of Surgical Procedures: Kinematics of surgical procedures is a specialized field of biomechanics that focuses on studying the motion and forces during surgical procedures. It helps in developing surgical tools and techniques that reduce the risks and complications associated with surgeries.
Kinematics of Robotics: Kinematics of robotics is a branch of biomechanics that focuses on studying the movement and control of robotic systems. It considers parameters such as joint angles, velocity, and acceleration of the robot during its operations.
"Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move."
"Kinematics, as a field of study, is often referred to as the 'geometry of motion' and is occasionally seen as a branch of mathematics."
"A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity, and/or acceleration of points within the system."
"Then, using arguments from geometry, the position, velocity, and acceleration of any unknown parts of the system can be determined."
"The study of how forces act on bodies falls within kinetics, not kinematics."
"Kinematics is used in astrophysics to describe the motion of celestial bodies and collections of such bodies."
"In mechanical engineering, robotics, and biomechanics, kinematics is used to describe the motion of systems composed of joined parts (multi-link systems) such as an engine, a robotic arm or the human skeleton."
"Geometric transformations, also called rigid transformations, are used to describe the movement of components in a mechanical system, simplifying the derivation of the equations of motion."
"They are also central to dynamic analysis."
"Kinematic analysis is the process of measuring the kinematic quantities used to describe motion."
"In engineering, for instance, kinematic analysis may be used to find the range of movement for a given mechanism."
"Working in reverse, using kinematic synthesis to design a mechanism for a desired range of motion."
"Kinematics applies algebraic geometry to the study of the mechanical advantage of a mechanical system or mechanism."
