  1. 1. Basics of Motion
  2. 2. What is Force? <ul><li>Force is a push or a pull </li></ul><ul><li>It moves us, the earth, and everything between </li></ul><ul><li>Can be a wind, a wave, or a shove from a friend </li></ul><ul><li>It is the power behind acceleration, deceleration, and the impact </li></ul>
  3. 3. Force is Related to Motion <ul><li>For every acceleration you need a force </li></ul><ul><li>Running you have the push of your feet on the ground </li></ul><ul><li>Falling you have the pull of gravity </li></ul><ul><li>A car breaking you have the friction of tires on the ground </li></ul><ul><li>Ex. A bow that is extended to full extent will shoot the arrow farther than if it wasn’t extended to it’s full extent. </li></ul>
  4. 4. Isaac Newton <ul><li>Born in 1642 </li></ul><ul><li>Was a mathematician and physicist </li></ul><ul><li>Started with him seeing a apple fall in an orchard </li></ul><ul><li>Conceived that the same force governed the moon and the apple </li></ul><ul><li>Made the three laws of motion </li></ul>
  5. 5. Newton's First Law <ul><li>“ An object at rest will remain at rest unless acted upon by a force and an object in motion will remain at a constant speed in a straight line unless acted upon by a force.” </li></ul><ul><li>So every acceleration needs a force to act upon it </li></ul><ul><li>Falling needs gravity, running needs the force from the ground, and a car breaking needs friction on the ground </li></ul>
  6. 6. Newton's Second Law <ul><li>“ F=ma” </li></ul><ul><li>It tells us that the force required is directly proportional to the mass being accelerated and the amount of acceleration </li></ul><ul><li>So a big mass requires lots of force and “fast” acceleration requires lots of force </li></ul><ul><li>A large force = a large acceleration </li></ul><ul><li>Apply smaller force for long time and it will accelerate “slowly” but after awhile it will go “fast” </li></ul><ul><li>Less force = less acceleration and more distance and time is required </li></ul>
  7. 7. Newton's Third Law <ul><li>“ Every action has an equal and opposite reaction” or “Every force has an equal and opposite force” </li></ul><ul><li>So when you are walking, the force your feet exert on the ground is matched by the ground so you don’t sink. </li></ul><ul><li>Ex. When you walk your feet push against the ground and the ground in return pushes against your feet. </li></ul>
