Describe the relationship between the impulse exerted on an object or system and the change in momentum of the object or system.

• Change in momentum is the difference between a system’s final momentum and its initial momentum. Relevant equation:
• The impulse–momentum theorem relates the impulse delivered to an object and the object’s change in momentum.
  • i. The impulse exerted on an object is equal to the object’s change in momentum. Relevant equation:
  • ii. Newton’s second law of motion is a direct result of the impulse–momentum theorem applied to systems with constant mass. F dp dt m dv dt manet == =    
  • iii. The impulse–momentum theorem also describes the behavior of a system in which the velocity is constant but the mass changes with respect to time. F dp dt dm dt vnet ==   
