If v(t) is negative, the particle is moving in which direction?

Explanation:
Velocity tells you how fast and in what direction position is changing. If v(t) is negative, the position is decreasing as time increases. Along a horizontal axis, that means moving to the left; along a vertical axis, it means moving downward. So a negative velocity indicates motion in the negative direction (left or down, depending on the axis you’re using). It’s not stopped, since the velocity isn’t zero, and the direction is determined by the sign of v(t).
