Give three examples of what happens with unbalanced forces? I give

Sinking of an ship due to unbalanced forces. An object sinks in water due to the unbalance between the upthrust and the gravitational force. Objects float in the water at balanced force conditions.

For example:
Hanging objects. The forces on this hanging crate are equal in size but act in opposite directions.

Floating in water. Objects float in water when their weight is balanced by the upthrust from the water.

Standing on the ground.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
