Now consider the interactions between the two objects that undergo a collision. Apply the Impulse-Momentum Theorem to explain the changes in the momentum of the individual objects and that of the entire system. Use appropriate physics terminology in your discussion. As a matter of semantics, we say that a force is exerted on an object by another object; an impulse is imparted to an object by another object; an object or system can have, gain, or lose momentum; momentum is transferred from one object or system to another object or system.
When there is motion is both directions, state which direction is positive at the START of the problem. For the impulse-momentum and the conservation of momentum problems: Plug your GIVEN VALUES into the equation FIRST then do the algebra. Use the following equations: F t = m vf -m vi m1 vi1 + m2 vi2 = m1 vf1 + m2 vf2 m1 vi1 + m2 vi2 = (m1 + m2) vf (m1 + m2) Vi = m1 vf1 + m2 vf2 3.)

An oatmeal cookie is dropped on the floor. Is this an inelastic collision? Why or why not? It is because the cookie and floor can be considered one object. It is because the cookie and floor are stuck together. It is not because there is not momentum involved. It is not because the cookie and floor do not move away together as a unit.
An insurance company is testing air bag safety. Car A has front air bags and Car B does not. In both cases, the cars are driven into a brick wall with the same momentum. In Car A, the dummy survives, but in Car B, the dummy does not. In terms of impulse and force, please explain this result. The dummy in Car B experienced a greater impulse and a greater force than in Car A. O The dummy in Car B experienceda greater impulse but the same force as in Car A. The dummy in Car B experienced the same impulse but a greater force than in Car A. O The dummy in Car B experienced the same impulse and the same force as in Car A. O Not enough information to determine.
