Impulse Momentum ctivity

In this lab, our purpose is finding the relationship between impulse and momentum on the same object.However, we need to review the definition about impulse. Impulse combines the applied force and the time interval over which that force acts.J=Ft
And momentum is the product of the mass and velocity of an object.
j=mv
Therefore, we tried to measure impulse and momentum on a object in elastic collision and inelastic collision.

And then, we made the graph that record the force in respect of time, so that we can determine the impulse, and we also get the changed velocity and the mass, so we also get momentum.

From this graph, we discovered the impulse and momentum are almost same.

And, for  inelastic collision, we let the cart to impact the rubber so that the cart would not turn back after collision.

And we measure the impulse and momentum on a object again, so we got the graph:

From the graph, we also discovered that they are almost same.

Therefore, when the object impact with a wall that almost not move, the impulse and momentum are almost same, whatever it is elastic collision and inelastic collision.
