Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.
the measured or measurable period during which an action, process, or condition exists or continues : duration. b. : a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.
In physics, time is defined as the measure of a change in a physical quantity or a magnitude used to quantify the duration of events. Physics is a branch of science that studies time, an important fundamental quantity that is a component of calculating and understanding other areas, such as speed, motion, and velocity.
While it is often referred to as an illusion, it seems as though it is not a nonexistent or false reality, but rather a human-made construct that helps us make sense of our experiences.
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock
Positions
Position (x) can be defined as the location of an object at any given time. The random set of dimensions wherein the position and motions of an item are represented is referred to as a frame of reference. Displacement is the change in the position of an object.
Position and Displacement. Position is the location of the object (whether it’s a person, a ball, or a particle) at a given moment in time. Displacement is the difference in the object’s position from one time to another. Distance is the total amount the object has traveled in a certain period of time.
To describe the motion of an object, you must first be able to describe its position (x): where it is at any particular time. More precisely, we need to specify its position relative to a convenient frame of reference. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference

Also, an analysis of motion can have many displacements embedded in it. If right is positive and an object moves 2 m to the right, then 4 m to the left, the individual displacements are 2 m and −4 m, respectively.
