Aristotelian vs. Galilean views of motion

• Motion - It is the movement or change in location of an object over time.
• Aristotle - He was one of the greatest intellectual figures of western history and the founder of formal logic, among other discipline
• ARISTOTELIAN CONCEPTS

  • Natural ( VERTICAL ) Motion
  • Violent ( HORIZONTAL ) Motion
  • Projectile Motion
• Natural ( Vertical ) Motion - The object will move up or down (vertical motion) and will return to its natural state based on the object's material or composition.
• Violent (Horizontal) Motion - requires an external force (push or pull) for the object to move.
• Projectile Motion - the motion of an object upon which the only force acting is gravity.
• Galileo Galilei - was a famous Italian scientist known for his contributions to astronomy, physics, mathematics and the scientific method.
• Galilean Conception

  • Vertical Motion
  • Horizontal Motion
  • Projectile Motion
• Horizontal Motion - An object in motion, if unimpeded, will continue to be in motion, and an external force is not necessary to maintain the motion.
• Horizontal Motion - an object can move freely in the absence of friction
• Friction - the force that acts between materials that touch as they move past each other
• Vertical Motion - In the absence of a resistance, objects would fall not depending on their weight, but in the time of fall.
• Projectile Motion - is a combination of uniform motion in the horizontal direction and uniformly accelerated motion in the vertical direction.
• Antiperistasis - the resistance of a medium in response to the movement of a body.
• impetus - a force or energy that permits an object to move.
• Acceleration - the rate of change of velocity per unit of time
• Law of Inertia - Newtons first law of motion
