Suction
Physical Action
Suction as a force often involves a physical action that causes a vacuum.
Using suction, the octopus attaches itself firmly to the rock.
Not Always Visible
Suction happens even when you can't see the force, like in syringes or toilets.
The plunger created suction that cleared the clog in the toilet.
Common Misuse
Don't confuse 'suction' with 'adhesion'; suction involves vacuum force, not sticky surfaces.
The gecko's feet use adhesion, not suction, to cling to surfaces.
