Momentum and Impulse

• Thing to consider in momentum

  •has mass

  •object is moving
• Formula of momentun


  P=mv
• What do you call the change of momentum?

  Impluse
• Force is needed toto change the momentum
• Bodies changes their momentum thought collision
• The force of impact is directly proportional to the momentum and inversely to the time of contact
• If the object has the same mass and speed there is no momentun
• In close and isolates system, the total momentum of an object before and after the collition is equal


  Law of Conservation
• Momentum cannot lost when collition happen but only transfered
• When two objects with different masses are moving at the same velocity they have the same momentum
• The amount of force applied to otherother is ewual to the amount of force you feel
• In any collision, there must be conservation of linear momentum but this can express itself in a variety of ways depending on the type of collision
• Elastic Collision -One in which the total kinetic energy of the system does not change , and colliding object bounce off after collision
• One in which the total kinetic energy of the system changes. Object that are stick together after collistion is perfect elastic

  Inelastic collision
