Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
negative nine is the value of negative nine
The opposite is: negative (the absolute value of negative 30).
No the Km can never be a negative value. The Km increases or decreases with temperature. An incorrect calculation can produce a negative value.
No, in physics, speed and displacement are scalar quantities that represent magnitudes and cannot be negative. However, the direction of motion can be indicated by assigning a negative or positive sign to the speed or displacement value.

Yes, acceleration can be a negative number. Negative acceleration means that the object is slowing down, or changing its velocity in the negative direction. It indicates a decrease in speed or a change in direction opposite to the initial motion.
Acceleration has a positive value if the velocity is increasing speed. Positive acceleration means the object is speeding up.

Measure the speed at two different points in time. Then take your first value and subtract the second value. A positive value means a gain in speed, a negative number is a decrease in speed, and a value of 0 means no change in speed. The value itself represents how much it has changed. To describe the the change as acceleration you need to divide the change in speed in meters per second, by the time it took in seconds. The SI unit for acceleration is meteres per second per second.
Speed is (distance covered in some time) / (time to cover the distance).Neither the distance covered in the time, nor the time duration, can be negative.If you'll say "Well what about moving backwards ?", then you have introduced the directionof motion into the discussion, and now you're talking about velocity, not speed. Velocity caneasily be negative, but speed can't.
If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.
No, the product of the multiplication of a positive and a negative value is negative.
The result will be a negative value.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
