Bryan Spelhaug Tues Lab 8:00am 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 Trials V initial m/s V final m/s Impulse s*N 0g 0.59 -0.42 0.1857 20g 0.52 -0.40 0.1910 40g 0.36 -0.31 0.2017 60g 0.47 -0.38 0.2196 80g 0.85 -0.71 0.2274 Calculations: some example calculations fuck you
