If a position and velocity have opposite signs, the particle is moving towards the origin. How is this so?
Can you explain why a particle with opposite signs for its position and velocity is moving towards the origin?
Sure, the position of a particle tells you where it is, while the velocity tells you how fast it is moving and in which direction. If the position and velocity have opposite signs, it means that the particle is moving towards the origin because the velocity is in the opposite direction of the position.
