In this unit, we put forces in the context of energy. We used LOL charts to demonstrate how energy is conserved over time, while also showing that it can be transferred to different forms like thermal, kinetic, potential, and elastic via heat, work, and radiating. How fast one can transfer energy is power.
Representing Energy Transfers with Bar (LOL) Charts
In this lab, a cart was put at an angle in front of a force sensor and was compressing a spring. Upon release, the energy that was elastic energy got transferred over time into kinetic and gravitational potential energy, eventually dissipating due to the forces of friction. This is because work was detracted within the system. Energy is conserved, but transferred to different forms via work.
These were the problems I originally got wrong on the quiz and now have been corrected, fixing the conceptual errors of what lies in and out of a stem, and how the different components of energy should add to the total.

Energy/time = Power
Not all objects lie on earth. Such objects feel gravitational potential amongst themselves. The amount of potential energy here is dependent upon the objects' mass and distance
