What is the difference between physical distance and time distance?

The difference is magnitude, how long the distance is.
Physical distance is measured in units like miles and kilometers, and are used for short distances.
Time distance is measured in the distance light travels in a unit of time. The units are usually the kilometers light could travel in one year, and they are used for very long distances.
Light travels 299,792.458 kilometers in one second. Then it must travel 60 times as far in one minute, 60 X 60 times as far in one hour, 60 X 60 X 24 in one day, and 60 X 60 X 24 X 365 in one year.
In other words light travels 60 X 60 X 24 X 365 X 299,792.458 kilometers in one year. That is 9,454,354,955,000,000 kilometers. That number is so huge that it is much easier to say one light year.
Alpha Centauri the nearest star to our solar system is approximately 4.22 light years away. Our galaxy the Milky Way is approximately 100,000 light years long.
Using a distance measurement would be terribly cumbersome for interstellar distances or the distance between galaxies (intergalactic distances) which are even larger, so we use time distances.

What is the minimum distance with maximum time difference between two countries?
The time difference is three and a half hours at the border between Afghanistan and China.
What is the difference in time and light years?
Time is a physical characteristic. A light year is a measure of distance, not of time. It is the distance that would be travelled in vacuum by light or other electromagnetic radiation. The distance travelled in outer space is nearly the same and is equal to approx 9.46 trillion kilometres.
How is the distance between a seismic station and the earthquake epicenter is determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
What is the time difference between somerset and London?
Distance from london to canberra is 10545 miles. It always vary according to the path chosen. It is the straight path between the two points.
What is the physical meaning of the area under the curve of the graph of velocity vs time?
The area under the speed/time graph between two points in time is the distance covered during that time.
What is the difference between distance time and speed?
SHITE
When a body is moving with uniform velocity what is difference between distance and time?
the distance will be equal to the time multiplied by a factor which is the speed.
What is the minimum distance with maximum time difference between two countries?
The time difference is three and a half hours at the border between Afghanistan and China.
Difference between velocity time and distance time?
Velocity is distance divided by time. So the value of the velocity-time plot at any point in time will be the slope of the distance-time plot at that point in time.
What is the difference between a speed vs time graph and a distance vs time graph?
The dependent variable.
What is distance between Colorado and Uruguay?
in miles it is 5964 miles, with a 4 hour time difference.
What explains the difference between spped and velocity?
Distance covred in unit time is called speed
What is the longest time difference between two countries?
The longest time difference would be between Tonga and Samoa. They can be 24 hours apart but are only 550 miles / 887km apart in distance.
What is the difference in arrival time between P and S waves equivalent to?
This value is related to the distance of the seismometer station from the earthquake's epicentre. The larger the difference in arrival times, the greater the distance.
What is the difference in time and light years?
Time is a physical characteristic. A light year is a measure of distance, not of time. It is the distance that would be travelled in vacuum by light or other electromagnetic radiation. The distance travelled in outer space is nearly the same and is equal to approx 9.46 trillion kilometres.
What is the difference between Velocity and Acceleration of an object?
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
What is the difference between physical education and practice?
Practice is on your own time either at home but not during school time. Physical education is during school time, it mostly is followed up with a grade.
