Question

What is the meaning of inversely proportional and directly proportional in easy meaning with one example of each. (In Science)?​

Answer 1

Answer:

Inversely propotional means that if one quantity increases than the second quantity decreases.

For example:

Speed and time are Inversely propotional to each other as speed increases, time decreases.

Directly propotional means that if one quantity increases than the second quantity also increases.

For example:

Speed is directly propotional to distance, as distance increases than speed also increases

Answer 2

Answer:

well it is the obvious question arises in every student but they never get clear answer but I will give you.

Explanation:

let us suppose the formula F = Kqq/ r²

it is the expression of electrostatic force

here you can see

F is directly proportional to q i.e., F is proportional to the degree one (power of q is 1)

now if we change the expression for our convenience as

$f \: = \frac{kqq}{ {r}^{2} } = k \frac{q}{ {q}^{ - 1} {r}^{2} }$

now you can see that q is not now directly proportional to F but is inversely.

are you observing the power of 'q' before and now, before it was 1 but now it is -1

if we read the previous original formula...

we read as

F is equal to K q q by r square

but if we read the new modified formula.

we read as

F is equal to k q by q inverse r inverse two..

now we can say that F is now directly proportional to q and inversely proportional to q inverse and r inverse 2..

simply it is the game of power ( exponent)

hope you have understood

it took my lots of time please follow and brainliest otherwise don't even thank only if you have understood...
