  2. Gravitational time dilation - Wikipedia

    en.wikipedia.org/wiki/Gravitational_time_dilation

    Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events, as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...

    Time you spent travelling can't be spend on studying or working. In that sense, time is money. Geographer Andy Nelson (University of Twente) created a map to calculate how much time is wasted. In transport economics, [1] the value of time is the opportunity cost of the time that a traveler spends on their journey.

    The present value is usually less than the future value because money has interest-earning potential, a characteristic referred to as the time value of money, except during times of negative interest rates, when the present value will be equal or more than the future value. [1] Time value can be described with the simplified phrase, "A dollar ...

  9. Gravimetry - Wikipedia

    en.wikipedia.org/wiki/Gravimetry

    Gravity is usually measured in units of acceleration.In the SI system of units, the standard unit of acceleration is metres per second squared (m/s 2).Other units include the cgs gal (sometimes known as a galileo, in either case with symbol Gal), which equals 1 centimetre per second squared, and the g (g n), equal to 9.80665 m/s 2.
