HOW DOES LIFEJACK WORK
Life jackets are designed with materials that can float in water, some have air spaces that trap the air when under the water. There are wearer's weight specifications for maximal result.
Like with a basketball/ balloon, the air is lighter than the water causing the water to push up against the life jacket. The greater the force when a person is wearing the life jacket, the greater the buoyancy force by the water. This is a classic example of Archimedes' principle.
