AI Thread Summary
Momentum is defined as the product of mass and velocity, represented mathematically as p = mv. It is a conserved quantity in a system of point particles interacting in an inertial frame of reference. Each particle has a specific mass (m) and velocity (v), and the total momentum of the system remains constant during interactions. Momentum is fundamentally understood as a measure of the quantity of motion of an object.

What exactly is "Momentum"?

Geez julie! You're smart let me tell ya:) lol I'm not sure what you mean by saying "what exactly is momentum" but i know for our class it's that little P thing...and it's mass 'x' velocity:) hopefully that helped you out;)

Consider a system of point particles bouncing around and off each other in an inertial frame of referance. Define a quantity massociated with each particle such that the quantity mv is conserved. Give the name mass to the quantity "m". It is found experimentally that such a quantity exists for each particle. Define the quantity p as p = mv. The quantity p is called the momentum of the particle whose mass is m and whose velocity is v.

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
