There are more protons in an oxygen atom than in a hydrogen atom, so any electrons being shared between them (as in the covalent bond) are more likely to be near the oxygen atom than the hydrogen atoms.
This results in a slight net negative charge surrounding the oxygen atom, and slight net positive charges surrounding the hydrogen atoms.
there has to be a negative charge in the molecule as there is a positive charge. there is a negative charge and when it and a positive charge gets together it forms something that makes the charge neutral
positive ions
Because of the way the hydrogens bond to the oxygen in water, the molecular geometry is a bent or angular shape, and the oxygen has 2 lone pairs of electrons. This makes the oxygen part of the water molecule rather negative relative to the hydrogen part of the molecule, which is rather positive. Thus, there is a separation of charge, and this is what makes the water molecule so polar.
Water has a negative end and a positive end because of differences in electronegativity of the elements that make up water. Waters molecular formula is H2O. Hydrogen is a very electron poor element, with only 1! Oxygen, on the other hand, is a more electron rich element with 6 electrons. This makes oxygen much more electronegative than hydrogen. Because of this difference, water molecules are polar, meaning they are very negative on one point, and very positive on another.
In a molecule of water, you have a bunch of unshared electrons on the oxygen side of the molecule (the negative end) and no electrons and two hydrogen nuclei on the hydrogen end (the positive end.) This makes for very strong polarity, since a positive end and a negative end can be thought of as poles. Fluorine, on the other hand, is a diatomic element consisting of two fluorine atoms covalently bonded together. This means each of the two fluorine atoms contribute one electron to the bond. The remaining six from each atom are on the other side of the molecule from the bond. Six on one side and six on the other means no difference in charge across the length of the molecule, so there are no poles.

A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
It's makes positive because positive is stronger than negative. Negative and negative is positive.
A negative and a positive when multiplied makes negative.
Unequal sharing of electrons in a water molecule causes the molecule to be polar.
Positive : makes life easier negative : makes us lazy
An ion does have a charge. That is what makes it an ion.
Multiplying something by a negative number makes it change signs. A positive number multiplied by a negative is negative therefore a negative * a negative is positive.
It makes a positive, since the two negative signs cancel each other out.

a water molecule is polar because their is an uneven distributive of electrons between the oxygen and hydrogen atoms. the negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
