Negative Velocity

[wraithseeker]

How do you know that a object's velocity is 0.00 or below meaning that is not moving at all?

You're confusing speed and velocity. Velocity is a vector, it has direction and magnitude. The speed is that magnitude. Speed is strictly positive, while velocity can be negative.

But when I get the length of the velocity vector, it can never get to negative and I think that the lowest is 1?

[Pengwuino]

The length is the magnitude, aka the speed, which can never be negative (of course it can be 0, that just means theres no movement).
