"The world is against me," he said with a sigh.
"Somebody stops every scheme that I try.
The world has me down and it's keeping me there;
I don't get a chance. Oh, the world is unfair!
When a fellow is poor then he can't get a show;
The world is determined to keep him down low."

"What of Abe Lincoln?" I asked. "Would you say
That he was much richer than you are to-day?
He hadn't your chance of making his mark,
And his outlook was often exceedingly dark;
Yet he clung to his purpose with courage most grim
And he got to the top. Was the world against him?

"What of Ben Franklin? I've oft heard it said
That many a time he went hungry to bed.
He started with nothing but courage to climb,
But patiently struggled and waited his time.
He dangled awhile from real poverty's limb,
Yet he got to the top. Was the world against him?

"I could name you a dozen, yes, hundreds, I guess,
Of poor boys who've patiently climbed to success;
All boys who were down and who struggled alone,
Who'd have thought themselves rich if your fortune they'd known;
Yet they rose in the world you're so quick to condemn,
And I'm asking you now, was the world against them?"

 

                                   

Why centripetal force is a real force

and why centrifugal force is a non-real force?

Deep

Firstly sorry for the typing mistake

Nowwhat i am saying is the same What i meant was changing angular velocity results in changing acceleration as a

And sid

I meant that acceleration also depends upon angular velocity along with linear velocity

then sid u mean that acceleration is not due to angular velocity

But, a=r²

DEEPANSHU

i DON'T THINK THAT IT'S BECAUSE OF VELOCITY tHAT'S BECAUSE i HAVE MENTIONED IN ALL TYPES OF CIRCULAR MOTION AND THAT INCLUDES UNIFORM C.M. WHERE VELOCITY'S MAGNITUDE IS CONSTANT AND HENCE ACCELERATION=ZERO

 

PLZ CORRECT ME IF I'VE COMMITED A MISTAKE.

Isn't it that in all types of circular motion the motion is accelerated due to changing angular velocity?

If I maybe wrong plz correct me.

but grbelli isn't it that if centrifugal force becomes more the circular motion will get complete

 

I think i haven't heard of plasmo reaction

 but I'll tell u about plasma reaction 

It isAlso known as thermonuclear reaction, this is a fusion reaction which occurs from the collision of two thermal plasma ions, rather than between injected (nonthermal) beam ions.

ok i accept your answer and it has cleared a wrong concept in my mind

But when will be the condition mg=N be satisfied.

consider a car crossing a convex bridge .

mg=gravitational force acting downwards

mv²/r =centrifugal force acting vertically upwards.

Then what happens at

m( v' )²/r=mg   where v'=maximum safe speed

 

During vertical circular motion of a body, suppose a sphere tied to a string is revolved along vertical circle

then, why the tension along the string at the topmost point is zero?

    please explain it in detail it's urgent.
