Definition and calculation of time
The formula for time is the ratio of the distance to the average speed, which can be described by the formula: t = d/s, where:
d= is the distance,
s = the average speed
Derivation of the time formula for t
In order to easily derive the formula for time, we can use the commonly known formula for speed – which can be found, for example, in a car speedometer. Speed is described in km/h, and km is the distance (d) and t is the unit of time.
Thus, transforming the formula for average speed s = d/t, we multiply it by t
then we have s*t = d, then we divide by d on both sides and get the final formula for time: t = d/s
Simply put, according to the time formula, to calculate the duration of a something motion, we divide the distance travelled by the average speed at which it is moving.
An example in which we use the time formula
Calculate the time taken by the driver of a car to cover a distance of 120km with an average speed of 60km/h
Data from the task:
d = 120km
s = 60km/h
Looking for
t = ?
According to the formula for time t = d/s, substitute into the formula:
t = 120/60 = 2
t = 2h
Answer: According to the time formula, the driver covered the distance in 2 hours.
In physics, time is a scalar physical quantity. With the help of the time formula, it is possible to determine the sequence of events travelled and the intervals between events that occur at the same time. The concept of time was the subject of physical and philosophical considerations of scientists such as Newton, Einstein, Leibniz, Barkeley, Plato, St. Augustine, Kant, Bergson, Husserl and Heidegger.
As time has progressed, we have come to understand: a moment, a segment of time, a point of time, duration, the set of all points and periods of time, and in the theory of relativity the fourth coordinate of space-time.
