In the electrical system of the US what is the difference between the neutral and the PE Ground?
US NEC: The neutral conductor is an insulated grounded conductor used as the current return in a circuit. The color designation for neutral is white. The protective ground (PE, protective - earth) is a non-insultated grounding conductor used to shunt fault current to ground, tripping the protective device. The color designation for PE ground is green. Neutral and PE ground are tied together at the distribution panel. PE ground is also connected to a solid earth ground, such as grounding rods driven into the earth. Downstream of the distribution panel, PE ground is never used to carry operational current. Any current flow on PE Ground, other than parasitic current, is considered a ground fault, which must be corrected. In fact, GFCI (Ground Fault Current Interrupting) breakers will trip when neutral current does not match hot current, an indication of PE ground current flow.
Besides the earth what things have a gravitational pull?
Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.
When a 1.5 kg ball hits the ground what is the Potential energy?
PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height above the earth in meters. When the ball hits the ground, it is zero meters above the earth, therefore its PE is zero.
What is the difference in Joules in the gravitational potential energy of a 7.75 kg book that is 1.50 m above the ground and a 9.53 kg book that's is 1.75 m above the ground?
The 7.75kg book as a PE of 113.93 joules and the 9.53kg book has a PE of 163.44 joules. A difference of 49.51 joules.
When does a object have the most kinetic energy?
In the case of a falling object, the instant before the object hits the ground. U = KE + PE; PE=-KE . Inversely, the object has the highest potential energy (lowest kinetic energy) at the starting point of the fall.

What is the fullform of PE on the basis of computer command?
There is no "PE" as in commands, but there is Windows PE.
What is the gravitational potential energy of a 55kg box that is 8m above the ground?
PE = M G H = (55) (9.8) (8) = 4,312 joules.
A 250-kilogram car is initially at rest at point A on a roller coaster track The car carries a 75-kilogram passenger and is 20 meters above the ground at point A Neglect friction?
⌂PE = mg⌂h ⌂PE = (250 kg + 75 kg)(9.81m/s^2)(20m) ⌂PE = 63765 or 6.4 x 10^4 J
What happens to potential energy at 0 kelvin?
It remains the same. The formula for determining PE is PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height above the ground in meters. Temperature is not a factor in determining potential energy.
