Experiment IX:
Impulse and Change of Momentum
Date:
11/4/10
Objective:
Momentum is defined as the product of an object's mass and velocity.
The
formula for calculating momentum can be written as P(momentum) equals the mass of
the object multiplied by its velocity.
The impulse is simply the change in momentum of
the system.
We will observe this theory by moving a glider on an air track that hits an
object then reverses direction.
Method:
For this experiment we will use a glider that is connected to an air track.
The
glider will be given a horizontal force (push by hand) in which the glider will hit a
bumper (the force sensor) and then change directions.
There will be five trials done.
The
first trial is the glider by itself followed by adding 20 grams of mass each additional trial.
For each trial we will collect the initial and final velocities along with the impulse. This
will be done by hooking up a motion detector on the other side of the air track.
Data:
mass glider = 211.5g
