Acceleration & Momentum

  1. 1. Making Things Go Ms. Shinkle October 5-6, 2007
  2. 2. Acceleration <ul><li>To accelerate an object, a force must be applied. </li></ul><ul><li>The force on the object must come from outside the object. </li></ul>
  3. 3. Acceleration <ul><li>If more force is applied, an object will be accelerated ____ </li></ul><ul><li>If an object is more massive it will be accelerated ____ </li></ul>more less
  4. 4. Accelerated Motion Graph
  5. 5. Positive & Negative Acceleration
  6. 6. Effect of Mass on Acceleration F = ma
  7. 7. Acceleration <ul><li>Difference in velocity over time </li></ul>Acceleration = final velocity – initial velocity time a = (v f – v i )/ t
  8. 8. Momentum <ul><li>Property of a moving object due to its mass and velocity </li></ul><ul><li>Momentum has a direction </li></ul><ul><li>Momentum is ZERO if object is not moving </li></ul>Momentum = mass x velocity p = mv
  9. 9. How Much Momentum? <ul><li>A slow moving elephant </li></ul><ul><ul><li>Although it has a small velocity, it has a lot of mass </li></ul></ul>Momentum = mass x velocity p = mv <ul><li>A bullet </li></ul><ul><ul><li>Although it has a small mass it has a very large velocity </li></ul></ul>
