Now this may sound silly, but what does it exactly represent? (i'm taking physics..getting an 'A'...no problem, but momentum came up) Now what exactly does momentum mean?? We think of force as a push or pull... We acceleration as change in motion (speeding up/down, turning..etc-etc...) We think speed as amt. distance/time.... But momentum??What is it---i need a definition OTHER than mass*velocity.... I need a definition other than a change in impulse (force*change in time) What does momentum PHYSICALLY (push/pull, speed up/down) represent? The closest thing in my head is "inertia with respect to velocity"-- But yeah....what does momentum PHYSICALLY represent? The product of mass and velocity...what does it MEAN??? ("physically-speaking")?
