Force & Motion 2

  1. 1. Force & Motion 2
  2. 2. Friction <ul><li>Friction is a force that opposes the motion of objects that touch as they move past each other </li></ul>There are 4 main types of friction each with there own set of Characteristics
  3. 3. Types of Friction 1 <ul><li>Static Friction </li></ul><ul><li>The friction force that acts on objects that are not moving </li></ul>
  4. 4. Types of Friction 2 <ul><li>Sliding Friction </li></ul><ul><li>A force that opposes the direction of motion of an object as it slides over a surface </li></ul>
  5. 5. Types of Friction 3 <ul><li>Rolling Friction </li></ul><ul><li>The friction force that acts on rolling objects </li></ul>
  6. 6. Types of Friction 4 <ul><li>Fluid Friction </li></ul><ul><li>Friction force that opposes the motion of objects through fluids such as water, air, and liquids </li></ul>
  7. 7. Gravity <ul><li>Gravity is a force that acts between two masses </li></ul><ul><li>Earths gravity acts downward </li></ul>
  8. 8. Falling objects <ul><li>Gravity causes objects to accelerate downward, whereas air resistance acts in the direction to the motion and reduces acceleration </li></ul>
