Answers
Step-by-step explanation:
Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝. ... For example, x and y are two quantities or variables which are linked with each other directly, then we can say x ∝ y.Other examples of direct proportion are: the cost of apples at $5 per kilogram. total wages earned at $20 per hour. amount of flour needed to make muffins (at 3 cups of flour for every 10 muffins)
Your Answer:
Direct proportion :
In simple terms we can say that;
Two quantities are said to be directly proportional to each other under 1 condition
The condition is ;
- If one quantity increases then the other quantity also increases.
- similarly, If one quantity decreases then the other quantity also decreases.
If any two quantities satisfy this above mentioned condition then they are said to be in direct proportional.
For , the first time this direct proportionality was been proved by Robert hooke.
Hence, this law is also popularly known to be as Hooke's Law .
Actually; Robert Hooke was an English philosopher who founded this law surprisingly.
He used an spring balance and weights to prove this law was correct.
And soon many philosophers accepted his law and soon it named as Hooke's law.
Examples:
1. When we take a spring balance and add weight to it . since increase in weight results in increase in readings. So , if we add more weight the increase in the weight will trend to the increase in the reading.
From this we can say that they are in direct proportional.
2. When trees increase in number then automatically the number of species will also increases. ( This example is daily life example)
3. In physics , A great scientist named Issac Newton stated that If a mass of the body increases then the inertia present in that body also increases. This is also in direct proportional
