    Newtons Second Law Balloon LabPhysicsUnit 4: Force

    Today you are going to investigate the relationship between the force acting on an

    object and the amount of acceleration the object experiences. You will also investigate the

    relationship between the mass of an object and the amount of acceleration it experiences

    given a constant force.

    You and your group will obtain the following:(Your group will only be allowed the 3 balloons, so be careful not to pop them!)

    a. You and your group will pick five different amounts of mass to test. (Mass

    includes the balloons mass and all of the masses you attach to the balloon.)

    You will blow the balloon up to the SAME circumference each time (you

    choose this circumference). Record each mass and the circumference.

    b. You will loop one end of the fishing line through the straw. Blow up theballoon to your chosen circumference and hold it shut (dont tie it shut). Tapethe balloon to the straw and hold the fishing line taut (completely horizontal).

    c. Measure and record the distance that the balloon moved.

    a. You and your group will pick five circumferences (forces) to test. You will

    attach the SAME amount of mass to the balloon each time. Record the mass

    and each circumference.

    a. You will loop one end of the fishing line through the straw. Blow up theballoon to your chosen circumference and hold it shut (dont tie it shut). Tapethe balloon to the straw and hold the fishing line taut (completely horizontal).

    b. Measure and record the distance that the balloon moved.

    a. In the investigation, the Independent Variable is

    ____________________, the Dependent Variable is ____________________, and the

    constant is ____________________.

    b. Use LOGGER PRO to create a graph of Mass vs. Distance Moved from questionMake sure to include all parts of a proper graph. Attach graph.

    c. From the graph you created, what can you say about the relationship betweentotal mass of the balloon and the distance it moved?

    d. In the investigation, the Independent Variable is____________________, the Dependent Variable is ____________________, and the

    constant is ____________________.

    e. Use LOGGER PRO to plot a graph of Circumference vs. Distance Moved. Makesure to include all parts of a proper graph. Attach graph.

    f. From the graph you created, what can you say about the relationship betweencircumference of the blown up balloon and the distance it moved?

    g. The circumference of the blown up balloon can be related to the ______________acting on the balloon, while the distance the balloon moved can be related to

    the __________________ that the balloon encountered.

    h. Based on your answers to (c) and (g), what is the relationship between massand acceleration?

    f. Why is there a difference in how hard the driver would have to push on thegas to speed up alone versus with three other people in the car?
