Air resistance on an object is also referred to as drag. The equation for drag force on an object takes the following form,
FD = (1/2) CD A ρ v2
where CD is the coefficient of drag for an object of that shape, A is the projected area normal to the direction of air flow, ρ is the air density, and v is the velocity of the air.
The force of drag, or air resistance, is therefore proportional to:
- the projected area of the object
- the density of the air
- the square of the velocity

Is there a direct or inverse proportion between voltage and resistance?
voltage is directly proportional to resistance, and the current is inversely proportional to resistance. According to Ohm's Law, current is directly proportional to voltage.
Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
Is resistance inversely or directly proportional to temperature?
Directly proportional. As temperature goes up, so does resistance (hence supercomputers being cooled to such low temperatures).
What is joule's law of heating?
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
Is there a direct or inverse proportion between voltage and resistance?
voltage is directly proportional to resistance, and the current is inversely proportional to resistance. According to Ohm's Law, current is directly proportional to voltage.

The statement that current is directly proportional to voltage and inversely proportional to resistance is known as whose law?
The statement current is directly proportional to voltage and inversely proportional to resistance is known as Ohm's Law.
Which variable is inversely proportional to the resistance?
If you have a conductor ... say, a copper wire ... and you keep its diameter and temperatureconstant, then yes, its resistance will be directly proportional to its length.
Do Power is directly proportional to resistance or inversely proportional to resistance?
It is both proportional and inversely propertional to resistance however I am not exactly sure why which is why I am searching Google ATM for answers.
How are current and resistance related are they directly proprtional or inversely proportional?
inversely proportional
Is resistance inversely or directly proportional to temperature?
Directly proportional. As temperature goes up, so does resistance (hence supercomputers being cooled to such low temperatures).
What is joule's law of heating?
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
What is blood flow directly proportional to?
Peripheral resistance
Why current is directly proportional to voltage?
Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.
Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
Is the current directly proportional to the change in temp?
hi! no the current squared is directly proportional to the change in temp, Joules Law
