Okay, so let's imagine we've got two objects that have different masses, but they have the same kinetic energy.
00:06
The question is which one would have the, what, the greater momentum, the one with a larger mass or the smaller mass.
00:13
You know, so, okay, so our kinetic energy, remember, is one -half mv squared, right? and our momentum is mv.
00:23
So let's just pick some numbers here, right? okay.
00:26
Let's imagine that we've got one kilogram and that it's going four meters per second.
00:32
And i think this will work, right? okay, well, our kinetic energy in that case is going to be one -half times one times four squared...
