Hi, in this question we need to explain the difference between dark t energy e and the work done w these three parameters dark energy and work done all have the same units that means all have the units of jules this also having jules this is also expressed in jules but what is the difference between these three.
00:33
That is what we need to explain.
00:35
First of all, let us consider the dark.
00:38
The dark is the product of the tangential force and the dark arm.
00:48
Dark arm is nothing but the radius of any shaft.
00:52
Now coming to the energy.
00:54
Energy is capacity to do work.
01:00
Capacity to do work.
01:05
Now, this energy may be in the form of stored energy or energy in transition.
01:16
The examples let us see later.
01:19
Now coming to the word done, word done is the product of the force and the displacement.
01:28
Let us say d.
01:31
Now, coming to the example for the torque, we can consider a shaft.
01:37
You can consider a shaft of diameter d and which is rotating in the clockwise direction.
01:45
When it rotates in the clockwise direction, the tangential force will be acting tangent to this shaft.
01:54
This is the tangential force we can say that ft and this is the radius of the shaft.
02:02
This radius of the shaft is considered as the torque arm.
02:07
Now coming to the werdon...
