Matter first qt

• Empedocles


  Arranged that all things are made up of 4 elements: fire, air, water, and earth
• Empedocles' view has been proved wrong as not all things are made of those 4 elements
• Instead all things are made up of atoms
• Demetrius


  Proposed the existence of atoms, small pieces of matter he called "atomes" which means "indivisible"
• Atoms


  • They are external and indivisible
  • They can separate by radioactive decay, which is "spontaneous fission"
• Protons


  Positively charged particles
• Neutrons


  Negatively charged particles
• When protons and neutrons clump together it makes a large amount of energy which makes it explode
• The modern atom is different from the early views on matter
• Positively charged part


  When they chupay bugether it makes a
• The modern atom

  Jhen Dalton
• Jhen Dalton opened the theory of the atomus

  2600 years
• He is also dubid as the Father of Atomic energy
• Dalton's theory


  • He explained that matter are composed of atomus
• Aristotle's view on matter

  Aristotle discovered motion first, (Natural and Violent Motion)
• Aristotle's motions


  • Natural motion- where the objects moves upward and downwards natuarly. The heavie the object is the more interia while lighter objects has lesser interia.
  • Violent motion- a product of pushing and pulling by humans, it is caused by something wether voluntary or involuntary, always requires force for it to move
• Galileo's view on motion


  All bodies meve and arccelerate regardless of its mass and size. Greater mass - greater interia, lesser mass - lesser interia. Interia is the amount of resistance to force.
• Newton's view on motion

  Motion and energy has a reletion-ship. Law of interia - all object remain at rest or in uniform motion when along a straight line unless acted by an external force
• Kinetic and potential energy

  Kinetic - Energy in motion, Potential - stored energy
• Friction is the force that ressists in motion when the surface of one object comes in contact with the surface of another
• Air resistance is the force that happens when air is pushing against a moving object
