Balloon Lab
Question: What variables affect the impact force in a collision and in what manner do they affect the force?
Purpose: to see how the three variables change upon the impact of force and collision.
Procedure
1) A water balloon is thrown (or dropped from) approximately 10 feet up into the air, caught and observed to not break. The same balloon is thrown 30-40 feet up into the air, and observed to break.
2) A not very massive (under filled) water balloon is thrown (or dropped from) about 20 feet up into the air, caught by the teacher and observed to not break. A very massive (overfilled) water balloon is thrown about the same distance up into the air, caught and observed to break.
3) A water balloon is thrown (or dropped from) approximately 50 feet up into the air, caught using a cradling motion, and observed not to break. The same water balloon is thrown about the same distance up into the air, allowed to hit the ground and observed to break. Students record their observations, identifying the independent variable (m, F, ∆t), the constant quantities, and the dependent variable for each demonstration.
Questions:
a.What effect does a ten-fold increase in ∆time have upon the subsequent force which is required to change an object's momentum (assuming other quantities are constant)?
There is an inverse relationship between the time and the force when the time was increased by X10 the force was divided by 10.
Row1 and Row2
b.What effect does a fivefold increase in mass have upon the subsequent force which is required to change an object's momentum (assuming other quantities are constant)?
The force required is increased five fold
Row 1 and 2 Show this
c.What effect does a two-fold increase in velocity change have upon the subsequent force which is required to change an object's momentum (assuming other quantities are constant)?
The velocity increased by x2 the force also as well increased by x2
Row 6 and 7
Conclusion:
Conclusion (Orville)
In the experiments done we noticed that the if one cradled the balloon the balloon wouldn’t pop. When the balloons weren’t cradled the balloons had a higher chance of bursting. These show that if one increased time (cradling) the amount of forced needed to be exerted in order to stop the balloon decreased allowing the balloon to not pop. Also mass affected the entire process as larger masses made the balloon fall faster thereby increasing force of impact meaning in order to successfully the change momentum one would need to a.) exert more force, or b.) increase time of change in momentum.
