conservation of momentum and collision

• Conservation of Momentum states that For a collision between object and object 2 is an isolated system, the total momentum of the 2 object before the collision is equal to the collision of the 2 objects after.


  Date
• Total Momentum before = total momentum after
• Exercises


  1. Pbefore = Pafter

  2. Mv before = Mv after
• Collision


  Happens when two objects comes in direct contact with each other
• Types of collision


  • Elastic collision
  • Inelastic collision
• Elastic collision


  • The total Kinetic Energy of the system does not change and colliding objects bounce off after the collision
  • Example: balls in billiards games
• Inelastic collision


  • The total kinetic energy of the system changes or converted into another Form of energy
  • Objects that stick together after the collision are said to be perfectly Inelactic
  • Example: collision of two cars
• Kinetic Energy may be lost during the collision when (1) it is converted to heat or other Forms of energy and (2) it is apent in producing deformation or damage
