magnetism is a force that can both attract and repell(pull/push), A MAGNET WORKS BECAUSE OF ITS MAGNETIC FIELD, A MAGNET HAS A POLARITY AND POLARITY MEANS THE MAGNET HAS TWO OPPOSITE SIDES, OR POLES THAT WORK DIFFERENTLY, EVERY MAGNET HAS A NORTH POLE AND A SOUTH POLE. AND THE FORCE OF A MAGNET FLOWS FROM THE NORTH TO THE SOUTH, CREATING A FIELD, THE MAGNET FORCE IS STRONG IN THE POLES AND WEAK IN THE CENTER, AN ATOM IS BALANCED AND HAS POSITIVE NUCLEUS AND NEGATIVE ELECTRONS., IF AN ELECTRON IS PULLED AWAY FROM ITS POSITIVE NUCLEUS, THE ATOM IS NO LONGER BALANCED, WHEN THE ATOM IS NOT BALANCED, IT CAN ATTRACT AND REPEL LIKE A MAGNET, CAUSING AN ELETROMAGNETIC FORCE, FRICTION IS A KIND OF MAGNETIC FORCE, FRICTION CAUSES ATOMS TO GAIN OR LOSE ELECTRONS, RUBBING YOUR HAIR ON A BALLOON AND RUBBING YOUR FEET ON A CARPET ARE EXAMPLES OF FRICTION, AN ELETROMAGNET IS A DEVICE THAT CAN GENERATE ELETROMAGNETIC FORCE, THE TELEGRAPH WAS DESIGNED WITH AN ELETROMAGNET, SCIENTISTS BELIEVE THE EARTH WORKS LIKE AN ELETROMAGNET, AS THE EARTH ROTATES, THE SPINNING  METAL CREATES AN ELETROMAGNETIC FIELDS, THE EARTH'S NORTH AND SOUTH MAGNETIC POLES ARE CLOSE TO THE NORTH AND SOTH GEOGRAPHIC POLES, A ROUGH SURFACE INCREASES RUBING , WHICH INCREASES FRICTION, BALACED FORCES ARE OPPOSING FORCES WHICH PREVENT WORK FROM BEING DONE., UNBALANCED FORCES MEANS THERE IS A GREATER FORCE THAT OVERCOMES OPPOSING FORCES RESULTING TO WORK , Unbalanced Forces do Work, Newton discovery the laws of motion , Inertia is a property of matter that makes it resist a change in motion, The greater the mass or amount of matter an object has, the more inertia it has, Mass, speed and direction are all part of an object moving energy ,
