1. Gravity
if you talked about Gravity as in "Force due to gravity"
SI unit for Force is Newton, Symbol N, ${\text{m"·"kg"·"s}}^{-} 2$
If you intended gravity as in "acceleration due to gravity"
Its unit is meter per second squared, ${\text{m"cdot "s}}^{-} 2$
2. Charge, electrical
Coulomb, symbol C
3. Potential Difference, assuming it is electrical
Volt, symbol V, ${\text{m"^2·"kg·s"^-3·"A}}^{-} 1$, (A is ampere)
4. Voltage
Volt, symbol V
5. Electric Field
volt per meter, ${\text{V" cdot "m}}^{-} 1$
