In the book, as one can read above, the are playing a game with rocks. In the movie, like you mentioned in your question, they are fighting each other. Later in the book, Gandalf does mention that "[He] must see if [he] can't find a more or less decent giant to block up [the pass leading to the Goblin lair] again.”
In The Hobbit, Stone-giants are described as hurling rocks at one another as in a game, during a violent thunderstorm. Their physical form was not described, nor was much else about them.
A Thunder Battle is the twentieth soundtrack of The Hobbit: An Unexpected Journey. It plays during the Battle of the Stone Giants during the Company's crossing of the High Pass.
Stone-giants are golem-like creatures that appear in the fourth level, hurling rocks at Bilbo as he tries to travel along a mountain path. They are completely made of stone, and their stones are dangerous.
Rather, they tend to be neutral, keeping to their cavernous homes and out of the business of most other creatures. Still, given their habitat, this is not always possible -- stone giants may be roused as antagonists or allies if pressures push them in that direction.

The Stone-giants were out, and were hurling rocks at one another for a game, and catching them, and tossing them down into the darkness where they smashed among the trees far below, or splintered into little bits with a bang.
What is the metaphor for the Stone Giants in The Hobbit?
During a storm, the Stone-giants emerge, and cast huge boulders about a rocky valley as part of a bizarre game. The difficulty of fitting Stone-giants (and all giants, for that matter) into Tolkien's world has led some to see the Stone-giants as a metaphor for crashing thunderbolts, or something similar.
Tolkien's monsters are the evil beings, such as Orcs, Trolls, and giant spiders, who oppose and sometimes fight the protagonists in J. R. R. Tolkien's Middle-earth legendarium.
Azog's forces use giant worms to tunnel underground towards the city of Dale, which Azog calls "earth eaters". When the creatures appear during the Battle of Five Armies, Gandalf identifies them as "were-worms".
When meeting with Thranduil, Thorin says, “Imrid amrâd ursul” – “Die a fiery death.” When Thorin then recounts the meeting to Balin from his prison cell, he states that he told Thranduil “to 'Ishkh khakfe andu null'” – “pour my excrement on his head.” Another dwarvish insult came from Gimli in The Fellowship of the ...
Why did Thorin go crazy? Thorin fell victim to the sickness of greed. Dwarves are known for being greedy and proud, and when he realized the treasure of Erebor was his, including the Arkenstone, he became ill with Dragon Sickness. He began to value his wealth more than his friends, family, and own safety.
Balin shouts, "this is no thunderstorm! It's a thunder battle!" A part of the rockside separates from a mountain in the distance, revealing itself to be a stone giant. It hurls a rock, this time catching its intended target: another stone giant. The dwarves are caught between two fighting giants.
Erebor, also known as the Lonely Mountain, was lost for 171 years before Thorin began his quest to reclaim his homeland. Following the destruction of Smaug and the Battle of Five Armies, the Dwarves freed the Lonely Mountain and settled there once more.
The Arkenstone of Thráin, also known as the Heart of the Mountain, was a great and wondrous jewel that was sought by Thorin II which had been discovered beneath the Lonely Mountain during the reign of Thráin I, and then shaped by the Dwarves.
The origin(s) of orcs were explained two different ways (i.e., inconsistently) by Tolkien: the orcs were either East Elves (Avari) enslaved, tortured, and bred by Morgoth (as Melkor became known), or, "perhaps ... Avari [(a race of elves)] ... [turned] evil and savage in the wild", both according to The Silmarillion.
The Dark Lord Sauron is the most powerful villain in Middle-earth. He is a Maia, one of the divine spirits who entered the world to aid the Valar in their work. Sauron is responsible for creating the One Ring, which grants him immense power and the ability to control others.
In the following and more serious revision of his mythology, Tolkien kept the same origin: in the Quenta Noldorinwa (1930s) it is written that Morgoth created the Orcs in Utumna, before the Awakening of the Elves: "the hordes of Orcs he made of stone, but their hearts of hatred".
Further, the mountain is a symbol of adventure in The Hobbit, and of Bilbo's maturation as an individual, while to the Dwarves, it stands for the gain of beauty in return for loss of life.
The Arkenstone of Thrain shows how a symbol's meaning can change over time. It first symbolizes family and ancestry to the dwarves, but as the story continues, it begins to represent greed. This greed of Thorin leads to the Battle of the Five Armies.
In J.R.R. Tolkien's novel The Hobbit, foreshadowing is used from the very first chapter when the narrator begins to describe the main character Bilbo Baggins, a hobbit who has both Baggins and Took blood in his veins. This is significant because in theory, hobbits are not the types to ever have adventures.
However, in the book, the giant's encounter is far more lighthearted and playful than this. They were 'hurling rocks at one another for a game' and catching them' and the dwarves 'could hear the giants guffawing and shouting all over the mountainsides.
What is the difference between a goblin and an orc?
Orcs are much bigger and usually serve as warriors whilst goblins are much smaller and are usually the much abused servants of more powerful creatures. And there are also “hobgoblins” which are bigger than goblins but smaller than orcs. This has its roots in European folk tales.
Hermes wore Hades' helmet and slew a Giant as he ran away, and Artemis killed another. Even the Fates killed a couple of Giants, fighting with clubs made of bronze. Finally it was all over. Zeus had struck down the rest of the Giants with his thunderbolts, and Hercules finished them off where they lay.
