👉 Pulsion is a concept in physics that describes the phenomenon where an object's gravitational pull or other force causes it to accelerate. This acceleration can be felt as a force, such as from standing up straight and moving one's feet forward or backward, or it can be perceived as a sensation, such as when someone feels their heart racing or sweating. The term is often used to describe the feeling of being under pressure or being in a state of stress, but it also has applications beyond physics.
