The development used differential geometry to describe a curved universe with gravity the study is called general relativity. Efforts to incorporate gravity into relativistic mechanics were made by W. This part of mechanics is special relativity. Acceleration, the change of velocity over time, then changes rapidity according to Lorentz transformations. For example, one can talk about the motion of a wave or the motion of a quantum particle, where the configuration consists of the probabilities of the wave or particle occupying specific positions. In general, the term motion signifies a continuous change in the position or configuration of a physical system in space. One can also speak of the motion of images, shapes, and boundaries. Motion applies to various physical systems: objects, bodies, matter particles, matter fields, radiation, radiation fields, radiation particles, curvature, and space-time. As such, everything in the universe can be considered to be in motion. Modern physics holds that, as there is no absolute frame of reference, Newton's concept of absolute motion cannot be determined. If an object is not in motion relative to a given frame of reference, it is said to be at rest, motionless, immobile, stationary, or to have a constant or time-invariant position with reference to its surroundings. 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. ![]() Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time. In physics, motion is the phenomenon by which an object changes its position with respect to time. ![]() The whirling motion of a Tanoura dancer, captured through long-exposure photography For other uses, see Motion (disambiguation).
