John Buridan and the Theory of Impetus

A set of vocabulary flashcards based on key concepts from John Buridan's theory of impetus, including definitions and explanations of terms discussed in the lecture.

Impetus

A motive force that is impressed in a projectile, determining its motion.

Antiperistasis

The theory suggesting that projectiles are moved by air rushing in to fill the vacuum left behind by the projectile.

Resisting Air

The air that opposes the motion of projectiles rather than aiding them.

Motive Force

The force that causes a projectile to move, which is distinct from the motion itself.

Natural Place

The designated position toward which a body is inclined to move under gravity.

Conative Quality

A quality impressed in a body, enabling it to move in a certain direction.

Succeeding Entities

The concept that movement involves successive interactions among multiple entities, rather than a single mover.

Gravity

The force that continually acts on a projectile, pulling it down toward its natural place.

Local Motion

The specific movement of a projectile through space, distinct from the impetus that drives it.

Experientia

Experiential evidence or observations used to support or refute theories.
