C

anonymous · Answer

wait.. how?? :O

anonymous · Answer

you are not talking about relativistic change now are you?!?! this isn't einstien's theory of relativity right?

anonymous · Answer

The faster you move, the heavier you get.

anonymous · Answer

he is not talking about relativity dude :P

anonymous · Answer

Oh, my bad sry :)

anonymous · Answer

my review is over impulse

anonymous · Answer

besides if relativity was included you could say mass too :D.. cause its really mass that changs.. :P

anonymous · Answer

ok israel.. never mind us.. 

you tell me which physical quantity do you think changes???

anonymous · Answer

i was actually thinking it was momentum, but i have no idea.

anonymous · Answer

you were thinking right.. can you tell me why though?

anonymous · Answer

well i thought that momentum is where it stay at rest but its moving so it keeps on losing its momentum!? is that right?

anonymous · Answer

noo :O.

what is momentum??

anonymous · Answer

he quantity of motion of a moving body, measured as a product of its mass and velocity.

anonymous · Answer

correct.. 
so you see.. momentum = mass times velocity.. 

so now as the velocity increases what happens to momentum?

anonymous · Answer

it rises/increases :) thanks

your welcome!!
