Answer:

How can Mass and Speed Influence KE?

The goal of this experiment was to determine how mass and speed influence KE. This is significant because you would know whether to add more or less mass/speed if you were in a position where you required something to move higher. We filled the bean bag with a set amount of water, then dropped it to see how much mass it had. After that, you kept track of how high the bean bag went. The same thing happened with the speed, but the amount of liquid in the bottle was the same; it was just dropped from different heights. My theory is that the KE will increase as mass increases. This is also true of speed; if the bean bag is dropped from a higher altitude, it will launch farther than before.

The data I gathered in the lab confirmed my hypothesis. When the bottle's height was increased, the bean bag rose higher than before. I also tested four different masses: 0.125 kilograms, 0.250 kilograms, 0.375 kilograms, and 0.500 kilograms. The bean bag rose higher each time it was placed on a greater bulk.

On the speed test, the bean bag would frequently go higher than the bottle drop point, but not always. Furthermore, when it was dropped from the same height each time, the results differed significantly, for example, when it was dropped from 1.28, the results were 1.14, 1.30, and 1.30. Mass, on the other hand, was all in the same number range, with the exception that the numbers were somewhat different.

I used the calculations KE= 12 mv2 and Ht v2/2g. The initial step was to compute an object's kinetic energy, using the formula m=mass v=speed. The second was to determine the height at which I needed to drop something in order to reach a specific speed, where Ht=Height and g=Gravitational Acceleration of 9.8 m/s2.

I utilized these to create tables that depicted relationships between various variables, such as mass and KE or speed and height. My data kept increasing the entire time I was conducting the lab; when there was more mass/speed, the table had greater numbers.

This proves that my first theory was correct: as m/s increases, KE increases accordingly because they are all linear. When the bean bag height exceeded the water bottle drop mark, I was taken aback.

To summarize, my theory was supported by my data. When more mass or speed was introduced, the data values increased. This means that if I wanted more kinetic energy for something, I'd know to increase the mass or the speed of the object that was supplying the energy.

This hypothesis is valid because when you have greater mass, you also have more energy. So, if you drop a baseball, it isn't very heavy, so it will only propel the bean bag a short distance. However, because a bowling ball is quite heavy and has a lot of energy when it falls, it would force the bean bag to fly very high.

To improve this experiment, I would create the lever from a smoother material so that energy is not lost due to friction from the wood rubbing together. Perhaps a scanner or video camera to better document how far the bean bag traveled. All of these would aid the lab in obtaining more precise results, and they might perhaps be used in the future.
