1. Background
An inelastic
collision is one where the total kinetic energy of the colliding
particles is not the same after the collision as it was before.
An example is a toy car smashing towards a wall. Before the collision,
the car moves fast and has lots of kinetic energy - and afterward,
it has zero kinetic energy. An elastic collision
is when the sum of the kinetic energy of all the colliding particles
is the same after the collision as it is before. An example of elastic collision
is a basketball bouncing off a backboard. The ball comes back with the
same level of kinetic energy as it had when it went forward, which means
it was an elastic collision. In this experiment, a group of students
will use 2 collision carts with a data-logging system to
study the characteristics of collision and the conservation
of momentum during the collision. The group will then present their
findings to the class.
