Question

i always wonder what momentum actually is?? everyone says that it is the product of mass and velocity but what actually it is?? is it something related to inertia???????????

Answer 1

They are right. It is the product of mass and velocity. It is important to consider it as a product that is also conserved. The momentum after any isolated event, is equal to the momentum before any isolated event, or (mv)sub1=(mv)sub2. I wish I had a better description for ya, but momentum itself is more/less a clever word for describing that product. When we derive things, that we don't understand, we often give them names or labels to make us feel more comfortable; a "singularity" for instance. "Momentum", much like "inertia", is one of those clever words or labels, although significantly easier to understand than a "singularity".

Answer 3

Momentum is not just a product of the mass and velocity.

Answer 4

I am not sure but I read once that it is how hard to stop a moving body . the larger the momentum-mass*velocity- the harder it is to stop the moving body.

Answer 5

The 3rd law is useful for conceptualizing momentum, but I caution against considering such things as "Forces". When you move into more advanced physics, you'll begin to define forces significantly different than simple products of mass and acceleration.

Answer 6

Newton 2nd law can be expressed as the time derivative of momentum.

Answer 7

momentum is not just a vector quantity described as the product of mass and velocity . it is a measure of tendency of a body to oppose change in its present state
