￼Mass,Velocity Relation :

As we know that ￼light travel at 3×108 m/s

Because it have no mass yet. It is the highest ￼

speed in the universe till now.

If we want to travel at speed of light we should Mass less.

Now by assumt that,

We start at point A at point a the mass is m and initial velocity￼ is 0.

Now assume that it slowly increase it's speed

Then, it will slowly decrease its mass by increase it's velocity.

It decrease as,

m - 1

m-2

m-3......

And finally, it reaches to light speed

It means V = C

there the mass becomes m-m =0

Then,from.above information we get that

mass is inversely proportional￼ to velocity.

* m=1/v*

Where, if mass increases then velocity decreases.

And vice versa.

Now,From Einstin equation

E = mc2

Now substituteing ￼ m =1/v in Einstein equation

We get,

E = 1/V×c2

Since v= c

E = C

There fore, at light speed the Energy of an object is equals to the Light Speed.
