GPE lab CEE By: Eh Dah Soe

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 there is more energy transferred to the sand when the distance is increased and than if I drop a smaller mass.

I know that when the mass increases the force is increased because a greater mass is being accelerated due to gravity at a rate of 9.81 m/s2. If " m*g" is increased, then since GPE=m*g*h, the potential energy is increased. My evidence supports this by when the mass was or 0.05kg hit the sand, the crater of the depth was 0.5 cm with energy use of 0.24 joules. The GPE increased when we added in more mass. The second data we took, our mass was 0.55kg with a 4cm depth of crater and energy use of 2.7 joules. I know that the height is increased, then the energy will be greater because of the more mass it have.

The reasons that because when the mass increases so does the GPE and there is more energy being used. Potential energy is stored energy so when we drop the about that is when kinetic energy is used because Kinect is energy works in motion.
