You might have heard many people saying that Oh no!You do not know such a common thing.But today you will know who and why do they tell you this.
So when you think about practicals , the first thing that might come to your mind is experiments [in science],making robots [in computer].But the actual meaning of practical is something that you understand and not that you have mugged it up.
Now think about a science textbook saying that –
A simple machine is a device with the help of which a force applied on one point is transmitted to another point with a convenient change of magnitude and/or direction.
This is what is written .Now a person who has only bookish knowledge and only mugs up would have written-
A simple machine is a device with the help of which a force applied on one point is transmitted to another point with a convenient change of magnitude and direction.
Here there is a slight difference in the and/or part.
But a person who is not in the world of books and understands things would write-
A simple machine is a device using which work is made easier as energy is transferred to another point.
So you can see the difference………..
For time being you can get good marks and be happy but later in life when you need the knowledge , you will not understand anything.
But in practical you might get 2-3% less than what you usually get but later you will realise its benefits……..
I hope you understood what I wanted to tell you.
Thx and remember this ^^^^^^^^^^^^^^^^ ||||||||||||||||||||||||
