According to kinetic molecular theory temperature is a measure of kinetic energy.There is absolute minimum temperature which occurs when something completely stop moving whereby temperature cannot become lower than this point. The absolute zero which has been extrapolated to exist at about -273 celsius while in kelvin scale is set such that absolute zero is 0 k thus kelvin is better inorder to avoid negative number when calculating.
Rheostats are pure resistances with a provision to vary the resistance connected in the circuit with a moving contact. Resistance do not have polarities

K.E = 1/2*m*v^2 = 1/2(500)(3)^2 = 2250 J
m*g*h = 500(9.8)(30) = 147000 J
2250 + 147000 = 149250
