Time is a physical property that measures and compares all motion in the universe. All motion in the universe has cause and effect, meaning that there is a beginning and an end to all motion in the universe. This cause and effect is the reason why time is observed to have one direction. Humans perceive this cause and effect as past, present, and future. The past is the totality of all completed motion. The present refers to all motion in progress. And the future refers to the inevitable end of all present motion as well as to all successive motion that will inevitably follow. Time measures both the internal and external motion of matter. The internal motion refers to the motion of the particles making up the atoms and molecules inside bodies. This internal motion is responsible for the formation and evolution of bodies as well as their inevitable and gradual decomposition into nothing. The external motion refers to the motion of those bodies through space. Time is basically all of history meaning that it is the history of the whole universe. Time is considered as the fourth dimension in Einstein's theories of relativity along with the three dimensions of space to form a unified continuum.

∙ 9y ago- The official SI definition of the second is as follows:
The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom - The SI base unit for time is the SI second. The International System of Quantities, which incorporates the SI, also defines larger units of time equal to fixed integer multiples of one second (1 s), such as the minute, hour, and day.

Acceleration is defined as the change in velocity devided by?
time for the change
Why speed is a distance divided by time?
That's how speed is DEFINED.
Why does the unit of time enter twice in the unit accereration?
It should be noted that an acceleration is not a velocity. Velocity is defined as distance per unit rate; thus, it has dimensions of length/time. Acceleration is defined as change of velocity per unit rate; thus, its dimensions are velocity / time, i.e., (length/time) / time.
What property of a wave is defined as the length of time between pulses?
pulse length
What is defined as displacement over change in time?
that is speed, or velocity if a direction is implied
What does predefined mean?
Already defined, previously defined.
When did Ups invent time defined deliveries?
UPS did not invent time defined deliveries, Federal Express invented it around 1981.
What is a memory performance?
it is defined by access time and cycle time
The era of Reconstruction in Texas is defined by which of the following characteristics?
it was defined as a time when local time was made to conform to rules made outside of Texas
How can speed be defined?
Distance divided by Time
How is speed defined?
The distance travelled divided by time. Distance/time = speed
What is defined as distance per unit of time?
"Speed" is.
What is defined as the change in velocity over time?
Acceleration
What is proximity?
Proximity is defined as nearness in space or time.
How is time calculated on other planets?
Time is a universal thing, it is always there it is always progressing at the same rate never moving backwards, time may be defined as anything. Before 1960 it was defined as a 'solar day', and a second was defined to be (1/60)*(1/60)*(1/24) of a solar day, then in 1967 we changed to the atomic clock which measures vibrations of cesium atoms, now one second is defined to be : 9192631770 times the period of vibration of radiation from the cesium-133 atom.like i said time may be defined by anything
Which term is defined as part of a resistance training program that systematically alters exercise over time?
Variation is defined as part of a resistance training program that systematically alters exercises over time.
What is the definition of jahilliyah?
jahilliyah is defined in Arabic as the time of ignorance
