Understanding The Space-Time

Time, Light, Mass, Gravity, Weight, Acceleration

Time :- Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future.

Light :- Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye.

Mass :- Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.

Gravity :- Gravity (from Latin gravitas 'weight'^[1]), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light^[2]—are brought toward (or gravitate toward) one another.

Weight :- In science and engineering, the weight of an object is the force acting on the object due to gravity.

Acceleration :- In mechanics, acceleration is the rate of change of the velocity of an object with respect to time.
