Thread: Theory of Relativity help

I have another problem that i am stuck on




m0 is the rest mass and c is the speed of light. What happens as v goes to c-

can anyone help me out i little i have been looking at this on too long and i am getting confused.

Thanks

As then

As the denominator of a fraction tends to 0 the variable being measured gets infinitely large, in this case m gets infinitely large.

Since division by 0 is undetermined then an object travelling at c would have undetermined (but very large) mass. This means that nothing can travel at c.


To summarise as

ok so if



would that be right or not

No, it wouldn't be right. Think about what happens when you square a number

oh ok ya that is right because anytime that you square a number it is always positive.
