Source sentences:
text: If an object is moving in a positive direction, then its momentum is considered to be positive.
text: If the velocity is decreasing in this direction then its momentum will be negative, that is , the momentum vector will point in the opposite direction
text: So, in the above problem you would say that the momentum is 'positive 8.0 kg-m/s', or '8.0 kg-m/s to the right'.
text: This is a substantially simpler calculation of the momenta of both particles; the reduced mass and relative velocity can be calculated from the initial velocities in the lab frame and the masses, and the momentum of one particle is simply the negative of the other.
text: If you define east as the positive direction of velocity, then if the velocity increases in this direction the momentum will be positive.
