What's the difference between propulsion and pulsion?
Propulsion
Definition:
(n.) The act driving forward or away; the act or process of propelling; as, steam propulsion.
(n.) An impelling act or movement.

(20) Density, cell wall percentage, osmotic pressure, and pH may affect propulsion.
Pulsion
Definition:
(n.) The act of driving forward; propulsion; -- opposed to suction or traction.
Example Sentences:
(1) They look like individuals who can not satisfy their fundamental pulsions without risking to confront other requests, and through this, they generate anxiety and guilt.
(2) Personality scales show that glaucomatous patients have difficulties in coping with aggressive pulsions and tend to react to affect loaded situations by a defensive or avoiding attitude.
