Lab 11: Conservation of Momentum
Purpose
To discover what happens to total momentum when objects collide
Background
You might think of conservation as relating to how much water or gas you use.
But conservation also means that conditions before and after an event do not
change. Conservation of momentum means that the total momentum of any
group of objects before an event is the same as it is afterwards. No momentum
has been lost and none has been gained. Although collisions may be elastic or
inelastic, and even if some balls bounce off at greater velocity than they started
with, energy really is conserved and total momentum remains constant.
Skills Focus
Graphing, interpreting data, drawing conclusions, making generalizations
Procedure
1. Start Virtual Physics and select Conservation of Momentum from the list of
assignments. The lab will open in the Mechanics laboratory.
Conservation of Momentum
2. The laboratory will be set up with two balls of the same mass on a table. You
will perform three experiments to look at the momentum of the system by
looking at the momentum of each ball within the system.
3. Trial 1: Two balls moving The masses of the balls are the same. The
velocities of the balls are the same in magnitude but opposite in direction,
toward each other. The balls start out ...
