This is pretty much like asking "What is the advantage of the number 5?" Gravity is an effect of the curvature of space-time by mass. It's a mistake humans typically make to think of everything in terms of "what is the purpose of this thing?"
becaus of the gravity of the earth
by spinning someone around
the sun gives us heat and holds the earth in place with its gravity

Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
Because the "ideal advantage" doesn't always consider all factors i.e. gravity, friction, heat/cold etc. It considers just the "ideals".
It is massless and it is not affected by gravity.
Legend in SRZG does not have a particular type. It is very basic, and its ONLY advantage is its stunt ranking. Aside that, it is not special, and has no abilities that other gear, such as Advantage-S (skates-grinding), have.
Gravity plays a key role in skiing by pulling skiers downhill, providing the force necessary to accelerate and maintain speed. Skiers use gravity to their advantage when navigating slopes and turns, and it also helps them generate energy for jumps and tricks. Overall, gravity greatly influences the speed, control, and dynamics of skiing.
Humans use gravity for various purposes such as generating hydroelectric power, allowing objects to fall to the ground (e.g. for construction or transport), facilitating water flow in irrigation systems, and providing resistance for strength training exercises.
by using certain mechanical objects, like a pulley, you can use the object's own weight to its advantage. Also, by exploiting gravity and the object's own weight, you can use inertia to roll the object down the hill or yet better in a free fall.
