Which airplane has more potential energy, a boeing 787 dreamliner having a mass of 2,450kg at 11,500 m above Earth, or a boeing 747 having a mass of 3150 kg at 9000 m above Earth?

Explanation:

For 787 dreamliner airplane,

Mass,

Height,

Potential energy of 787 dreamliner airplane is given by :

For a boeing 747,

Mass,

Height,

:

Potential energy of a boeing 747 airplane is given by

So, the potential energy of a boeing 747 airplane is more than the 787 dreamliner airplane.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).
