## Frequently Asked Questions

What are functions of time in physics?

Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics, it is a scalar quantity (often denoted by the symbol ) and, like length, mass, and charge, is usually described as a fundamental quantity.Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent ...

How do you define time?

Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.

What is the meaning of 'moment' in physics?

cross-product indicates an axis and gives a notion of rotational direction: clockwise vs counterclockwise. Moment is basically a measurement of how the mass is distributed about a point or axis. The larger the values, the more torque is needed to spin it. You would want to calculate about an axis if you're designing a rotating part.

What is mean by elapsed time in physics?

Elapsed time itself (squared) is subtracted from the spatial distance (squared) in ordinary, non-complex arithmetic. Elapsed time is negative distance. Time is negative space. Add to that the fact that gravitational potential is negative mass-energy, and you have a nice zero-energy universe.
