Does increasing momentum while keeping velocity constant decrease mass?

[Gorn]

Hello..

P = MV is the equation for momentum...in order to get the mass a rearrange the equation

such that it looks like this: M = P/V now as an example let's suppose P = 10 and V = 10

So..for example I get M = 10/10
M = 1kg

Questions: What are the 'terms' for momentum and velocity in this equation?

Lets suppose for argument sake that I double the momentum so P = 20 & V =10.

I then come to a conclusion that I do not believe is accurate that if I increase the momentum of an object but not its velocity at the same time I have a decrease in mass ..in this case of 1/2 kilogram? Is that accurate?

Am I correct in assuming that if there is an increase in momentum there is a direct and corresponding increase in velocity?

Is it accurate to conlude that no matter what the increase in momentum there is NO increase in mass?
Thanks for any and all answers
Bye

But you have an increase in mass, m=20/10=2kg. Which is what you would expect.
