Magnitude
In physics, magnitude is described in simple words as 'distance or quantity'. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Equilibrium
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
