HYPOTHESIS: If I drop the mass from a lesser height, then this height will give less joules of energy to the sand.

CLAIM: In class today, my group we did a Falling Masses Lab, by using sands, a meter stick, a data to takes notes, a gram holder. We measured the height by dropping more mass to measure the height into our data. Which we think will give more joules of energy to the sand.

EVIDENCE: In the data or Dropping Masses Lab, for our groups first trial, we increased the height by .1m (10 cm). The first trial we had a distance of .10m and dropped at 70kg. Then we had the GPE of .6867 joules. Our last one we did was, a distance of .90m and dropped a mass of 70kg again. The GPE we had was, 6.1803 joules.

EXPLANATION: Supporting my claim, objects being falled at a higher height will have a higher GPE ( mass X “gravity” X height ). According to my groupes data, the weight which is 700 grams ( 70 kg ) was dropped from .7 m ( 70 cm ), a GPE of 4.8069 joules, a depth of crater which made, 4.2 cm. Meaning that, objects Falling at higher height have a stronger impact force then objects falling at a shorter height. So objects at a higher height have a higher Potential Energy, Potential Energy is the Energy of an object because if it's position. According to the textbook, “The more an object weighs or the greater the object height the greater its gravitational potential Energy”. So if you you want to have more gravitational energy, then increase the height, because being in a higher height, will mean you could have a higher GPE.

GPE EQUATION: Mass X Gravity(9.81) X Height

FURTHER INVESTIGATION: We should try to drop our Lab by going places to places, meaning the environment around from us. Or have the same person drop every time, or different.
