Where does the potential energy of rocket goes when it escape from the influence of the earth
Nonamiya [84]

The potential energy of a rocket increases when its escapes from the influence of the earth. It increases when it escapes the earth's boundary.

<h3>What is escape speed?</h3>

Escape velocity or escape speed is the minimum speed required for a free, non-propelled object to escape from the gravitational pull of the main body and reach an infinite distance from it in celestial physics.

It is commonly expressed as an ideal speed, neglecting atmospheric friction.

If a spacecraft is launched from the moon at the escape speed of the earth then the value of escape speed will be the difference in both the velocities.

An object's height above the zero position directly relates to its gravitational potential energy.

The kinetic energy of motion is converted into gravitational potential power as your rocket ascends.

The rocket possesses gravitational potential energy as it climbs because it is becoming farther away from the Earth's surface, much as a positive and negative charge moving apart.

The potential energy of a rocket increases when its escapes from the influence of the earth. It increases when it escapes the earth's boundary.

What would most likely happen if the power lines in a petroleum power plant were broken
Vaselesa [24]
<span>Customers would not get electricity. If the transmission lines [heavy power] leaving the plant broke [zap], it's just fix the transmission lines. But if the generators or main switch gear were lost, so the plant itself has no power, it can get ugly. </span>
