1. CONSERVATION OF LINEAR
MOMENTUM

2. CONCEPT OF MODEL
This model explores the concepts of momentum and conservation of
momentum. Existing theory asserts that momentum is conserved. In
this model we will explore qualitatively the conservation of
momentum and will calculate the momentum before a collision and
the momentum after a collision of a coin and another coin. These
collisions will be run for three pairs of coins, each pair will be similar
in mass.

5. CONCLUSION
In physics, the term conservation refers to something which doesn't change.
This means that the variable in an equation which represents a conserved
quantity is constant over time. It has the same value both before and after
an event. Conservation of momentum is a fundamental law of physics which
states that the momentum of a system is constant if there are no external
forces acting on the system. It is embodied in Newton's first law (the law of
inertia). Conservation of momentum is the general law of physics according
to which the quantity called momentum that characterizes motion never
changes in an isolated collection of objects; that is, the total momentum of a
system remains constant. Momentum is equal to the mass of an object
multiplied by its velocity and is equivalent to the force required to bring the
object to a stop in a unit length of time. For any array of several objects, the
total momentum is the sum of the individual momenta. There is a
peculiarity, however, in that momentum is a vector, involving both the
direction and the magnitude of motion, so that the momenta of objects
going in opposite directions can cancel to yield an overall sum of zero.
