Yes Work can be positive or Negative.
when work is positive and when playing is negative
You can get the positive and negative wires for a class project at a store that sells the Physics apparatus.
what is positive and negative
because gravity is a force that acts down on an object. In physics up is positive and down is negative
In this case, V would be negative, and work w would be positive.

No, this will not work. Postitive to Negative/Negative to Positive will work.
what is positive and negative
Positive.
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.

If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
negative work
A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4
what I mean is, the alcubierre drive needs negative energy to work so what are the properties of negative energy
In this case, V would be negative, and work w would be positive.
