Momentum (or what I think it might be)

This week we will be talking about linear momentum and collisions. So here is what I think momentum is, straight off the bat, before we get into the real deal. I think momentum is the force of an object in motion— like a pendulum or that Chinese junk ship that Johnny Depp overturned in the third Pirates of the Caribbean movie. Momentum seems like such a loaded word: I am not sure what the most accurate definition of it would be, but it seems to be that momentum would have to do with both magnitude and direction. An example of momentum could be the force (?) behind the ball in a golf tournament, or the motion in a washing machine, right? I'm not too sure... this is just what I think so far, but I'm pretty sure momentum has to do with that sort of thing. We'll figure that out this week.

Maybe my sister is in momentum...? If she is moving with magnitude and direction...
