GPE LAB CEE By: snow white

Testable Question: How does mass of a falling object affect the amount of energy transferred to sand? How does the height of a falling. Object affect the amount of the energy transferred ?

The concept that was learned in the GPE lab was that the more mass the falling object have the more energy is transfer to the sand. Another concept that was learned in the GPE lab was when the height or distance is farther from the sand there more energy transferred to the sand. My mass data shows that when the mass of the object is .05kg the GPE was .0.12 Joules. When the mass of the object was 0.5kg the GPE was 2 Joules. For my height data when the distance was .2 meters away the GPE was .02 joules. Then when the distance was 1 meters the GPE was 2.6 joules. As you can see the GPE increases when the mass of the object and the height of a falling object increased from my mass vs. GPE and height vs. GPE graph. The reasons why the more energy transferred to the sand when there more mass and when the height and distance are far from the sand because potential energy, GPE, kinetic energy , and the transfer of energy. Potential energy is when an object can store energy as the result of its position. So when the height is far from the sand the gravity pulls it down which becomes kinetic energy ( Kinetic energy is an object that possesses due to motion). The mass put in weight when the gravity pulls and and the energy on the object left the depth of the sand to be deeper as you can see in the graph the sand the more mass the deeper the sand will be.
