Explanation:

To summarize using the two - column method:

Column 1: Potential energy

• Definition: Potential energy is the energy an object has due to its position or arrangement in a system.
• Gravitational potential energy:
• When an object is higher, it has more gravitational potential energy (because it has the potential to do more work when it falls).
• When an object is lower, it has less gravitational potential energy.
• Equation for gravitational potential energy: The formula is $E_{g}=mgh$, where $E_{g}$ is gravitational potential energy (in joules, J), $m$ is the mass of the object (in kilograms, kg), $g$ is the acceleration due to gravity (approximately $9.8\ m/s^{2}$ on Earth), and $h$ is the height of the object above a reference point (in meters, m).

Column 2: Arrangement of objects

• Pumped hydro system energy dependence:
• 1. The mass of the water (more mass means more potential energy, as seen from the $m$ in the $E_{g}=mgh$ formula).
• 2. The height difference between the upper and lower reservoirs (a greater height difference means more potential energy, as seen from the $h$ in the formula).
• Equation breakdown:
• $E_{g}$: Gravitational potential energy (J)
• $m$: Mass of the object (kg)
• $g$: Acceleration due to gravity ($m/s^{2}$)
• $h$: Height above reference (m)

Answer:

Potential energy	Potential energy in a system
Gravitational potential energy	- Higher object: More potential energy<br>- Lower object: Less potential energy
Equation	$E_{g}=mgh$
