THE ABSOLUTE TIME
CLASSICAL MECHANICS
ABSOLUTE SPACE AND TIME
Absolute space and time are a concept in physics and philosophy about the properties of the universe. In physics, space and absolute time can be a favorite setting.
Before Newton, a version of the concept of absolute space can be seen in Aristotelian physics. Robert S. Westman writes that absolute space can be seen in a "damf."
NEWTON
According to Newton, absolute time exists independently of any perceiver and progresses at a consistent pace throughout the universe. According to Newton, humans are only able to perceive relative time, which is a measure of perceptible moving objects (such as the moon or the sun). From these movements, we deduce the passage of time.
NEWTON
To support his views, Newton gave a few examples: According to Newton, a solitary rotating sphere can be deduced to rotate about its axis relative to absolute space by observing the swelling of its equator and a solitary pair of spheres connected to it. a rope can be deduced to be in absolute rotation around their center of gravity by observing the tension in the rope
CLASSICAL MECHANICS
Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machines and astronomical objects such as spacecraft, planets, stars, and galaxies.
If the current state of an object is known, it is possible to predict by the laws of classical mechanics how it will move in the future (determinism) and how it has moved in the past (reversibility).
DESCRIPTION OF THEORY
For simplicity, it often models real-world objects in the form of point particles. The motion of a point particle is characterized by a small number of parameters: position, mass and forces applied to it. Each of these parameters is discussed in turn.
It assumes that matter and energy have defined and known attributes, such as location in space and speed. Non-relativistic mechanics also assume that forces act instantly.
Space and time in classical mechanics
In general, the matter that surrounds us is in a continuous process of movement, and movement as a way of existence of matter is realized in space and time.
SPACE
Space is homogeneous and isotropic, meaning its properties do not change with the translation or rotation of a physical system. In terms of time, it is homogeneous, which means that on the one-dimensional axis of time, time flows are the same.
TIME
The temporal landmark consists of a "clock" associated with the spatial landmark. By "clock" we mean a physical process, whose events are taken as a benchmark for defining the sequence that characterizes any other set of events.
MOVEMENT DESCRIPTION
A spatial landmark and a temporal landmark are needed to describe movement or rest. The spatial landmark consists of the system of physical objects in relation to which the position of any material point is specified, or in general, of any physical object.
