A Bomb Jump is when Samus gets hit in Morph Ball with a Morph Ball Bomb. Their main purpose is to propel Samus vertically while in Morph Ball.

How Bombs Work

Metroid Prime 1

Morph Ball Bomb blast radius.

Bombs have a Bomb Counter whose initial value is 3 as well as a Bomb Refill Timer. When a Bomb is laid the counter decreases by 1 and the timer begins to count down from 3 seconds. The bomb that is laid can then be hit anywhere within this figure shown. Note this is slightly smaller than the full size of the bomb. This means Samus cannot get hit if she is too far below a bomb. The radius of this figure is .7 units, with Samus being unable to hit the bomb if she is located half the radius or .35 units below where the bomb was laid. Hitting a bomb gives samus a fixed vertical propulsion of just over 23.5 units. Underwater samus cannot bomb jump very well without the Gravity Suit. She is only giving a very tiny vertical propulsion of 8.7 units which is also quickly diminished because of water physics. By laying a bomb and starting the Bomb Refill Timer, Samus can time a Bomb Jump so that her bomb counter refills during the bomb jump. This allows for Bomb Jumps of up to 5 bombs. Being able to continuously refill past 5 bombs is known as Infinite Bomb Jumping.

One Bomb In Air Rule

Starting from the Wii version of Metroid Prime and onwards, an additional rule was added that Samus cannot hit more than 1 bomb in the air a time. This was likely to prevent the player from doing mid-air Bomb Jumps using Spring Ball. One quirk of this is that some rooms such as Hydro Access Tunnel and Waste Disposal turn off this rule to allow the player to progress normally through underwater Morph Ball tunnels.
