The friction whenever an object moves through a fluid is called fluid friction. Liquids and gases are fluids. Air exerts frictional force on cars, buses, aeroplanes, rockets, birds, etc. moving through it. Water exerts frictional force on objects like boats, speedboats, ships, fish, etc. which move through it.

The force which always opposes the motion of one body over another body is called frictional force or friction.

Direct variation:

If two quantities increase or decrease together in such a
manner that the ratio of their corresponding values remain constant, we say  that the two quantities vary  directly.

In other words x and y are said to vary directly if X/y = k
, where k is a positive constant.

In direct Proportion

x/y= k


x=ky

So we can find value of k from known values, and then use the
formula to calculate the unknown values

 

 Inverse variation:

Two quantities x and y are said to vary inversely or
indirectly if an increase in x  causes a
decrease in y and a decrease in X causes an increase in y in such a way that xy
remains constant.

In other words x and y are said to vary indirectly if x y =
k, where K is a positive constant.

In inverse Proportion

xy= k


x=k/y

So we can find value of k from known values, and then use the
formula to calculate the unknown values

 

When two quantities x and y are in direct
proportion (or vary directly) they are also written as x∝y.

When two quantities x and y are in inverse proportion (or vary inversely) they are also
written as x∝ 1/y

==========================================================

Solution:

Let the charges be x1 , x2, x3, x4

x1= 60/4= 15

X2= 100/8= 12.50

X3=140/12= 11.67

X4= 180/24= 7.50

x1 ≠ x2 ≠ x3 ≠ x4

Here, The charges per hour are not same ,
Hence the parking charges are not in direct proportion to the parking time.
