The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
it decreases because you need to give energy (heat) to a liquid to become gas.
gravitational potential energy
The total energy of a satellite doesn't change. At its closest approach to the planet, it has the most kinetic energy and the least potential, whereas at its furthest retreat from the planet, it has the least kinetic energy and the most potential. But their sum ... the satellite's total mechanical energy ... is always the same. (It may gain heat energy when the sun is shining directly on it, and lose it when it's in the planet's cold shadow, but neither of those changes affects its orbit.)
kinetic energy depends on speed an potential energy depends on height and mass
they are both measured in joules
Potential energy turns into kinetic energy.
The Potential energy decreases as r increases.
The energy of the photons decreases as the wavelength increases
Potential energy turns into kinetic energy when an object at rest begins to move. As velocity increases, KE increases and PE decreases.
As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.
Its final velocity will be zero when it reaches maximum potential energy.

Kinetic energy increases whilst potential energy decreases. Total remains constant
For example, when an object falls, its potential energy decreases, but its kinetic energy increases, i.e., it falls faster and faster.
As the ball returns to its original shape, kinetic energy decreases and potential energy increases.
no. if an object moves faster its kinetic energy increases but at the same time its potential energy decreases.
Kinetic energy increases; potential energy decreases, because the object is now in motion
The amount of kinetic energy increases.
