The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
Elapsed time refers to the time that passes between two events.
Elapsed time
Comparison of waves going through the solid inner core and those just skimming it can show the rotation of the inner core.
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
problem of comparison of national income between time periods
The ratio between two different quantities is the rate.Usually, the second unit is a measure of time.
Scalars Examples: Mass, Charge, Temperature, Density, Energy, Units of time like hours, minutes and seconds
A ratio between two (usually) different quantities is the rate. Usually used to describe something compared to a quantity of time.
Base quantities are independent and cannot be expressed in terms of other quantities, while derived quantities are dependent and derived from combinations of base quantities. Base quantities are fundamental in a system of measurement, while derived quantities are derived through mathematical relationships. For example, length is a base quantity, while speed is a derived quantity that depends on both length and time.
any rate is a comparison of two changing quantities, usually one of them is time. distance vs time is a rate called speed wit units of meters per second, or miles per hour, or many others
Unless you give the speed, there is no sensible comparison between time and distance.
Then is used to relate to time and than is used when there is a comparison to be made.
Examples of base quantities include length, mass, time, electric current, temperature, amount of substance, and luminous intensity. Derived quantities are those that are defined in terms of base quantities, such as velocity (length/time), acceleration (length/time^2), force (mass * acceleration), and energy (mass * (length^2/time^2)).
Contemporary comparison refers to evaluating or contrasting something with other things that exist in the present time. It involves analyzing similarities and differences between current entities, ideas, or trends.
Fundamental quantities are independent and cannot be defined in terms of other quantities, such as length, mass, and time. Derived quantities are defined in terms of fundamental quantities, such as velocity (defined as distance divided by time) and acceleration (defined as change in velocity divided by time).
distance over time= speed displacement over time = velocity Difference between the two- distance and speed are scalar quantities (described by magnitude only) while displacement adn velocity are vector quantities (described by both magnitude and direction).
