Make-up
Remember: Labs are always more
interesting/fun when you are in class!
Instructions:
What are we doing in this lab?
In this lab, you will test Newton’s 1st law of inertia: Objects with mass have inertia.
The more mass an object has, the more inertia. The more inertia an object has,
the more difficult it is to accelerate an object with a force.
We will use a balloon as our object. The air inside will provide the force.
Questions to test today:
1) What happens to the inertia as mass is added?
2) What happens to the velocity if the force (air amount) remains the same?
No masses

Predict:
What’s going to happen in the experiment?
Consider what you have learned about Newton’s Laws of Motion…
What does inertia actually mean?
More inertia means what for motion?
So as we add mass, what can you predict will happen to the velocity of the balloon?
Zero extra mass
= what velocity?
2 extra masses
= faster or slower?
4 extra masses
= faster or slower?
6 extra masses
= faster or slower?

Which test had the slowest? Does this make sense?
Based upon what you have observed, what effect on velocity does more mass have?
