In mathematics, or physics, if one quantity is proportional to the other, that means that if one quantity increases by a certain factor, the other quantity increases by the same factor. For example, if"y" is proportional to "x", and "x" increases by a factor 10, then "y" must also increase by a factor 10. Any relationaship that does NOT follow this rule is NOT proportional.
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
Direct. For example, if a number is inversely proportional to something, it increase as the other one decreases. Ifa number is directly proportional to something, it increases as the other one increases.
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
Example of inverse proportion is: Density = Mass/Volume Because the formula represents that the density is directly proportional to the mass while density is inversely proportional to volume. Remember that inversely proportional means that if variable A increases, the variable B decreases, and if variable B increases, the variable A decreases.
In a directly proportional relationship, as one variable increases, the other variable also increases at a constant rate. In an inverse proportional relationship, as one variable increases, the other variable decreases at a constant rate.
Mass is proportional to momentum. Momentum is the product of mass and velocity. When mass increases, momentum increases.
Yes, the entropy of the universe increases when a system undergoes a reversible process.

Voltage is directly proportional to current, meaning that as voltage increases, current also increases and vice versa, as per Ohm's Law. However, voltage is inversely proportional to resistance, meaning that as voltage increases, resistance decreases and vice versa.
Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.

Perimeter is proportional to the linear dimensions, so it increases by 3x .Area is proportional to (linear dimensions)2, so it increases by 9x .
Frequency, when referring to waves, is directly proportional to the velocity of the wave. Frequency in inversely proportional to the wavelength.
The wavelength of an electron is inversely proportional to its speed and directly proportional to its mass. This means that as the speed of an electron increases, its wavelength decreases, and as the mass of an electron increases, its wavelength also increases.
Speed is directly proportional to energy in case of Einstein equation.
They're proportional; as temperature increases volume increases.
