In unit 8, we learned about work. Work is defined as the change in energy and can be found by multiplying net force and displacement. The unit for work is joules, or kgm/s. We learned how to calculate for gravitational potential energy (energy an object could have due to its position in a gravitational field) and kinetic energy (energy an object has while moving.) We also learned about spring potential energy. To be able to find spring potential energy, you must know the spring constant, or k.
When graphing on a force vs distance graph, the slope is k and the area under the curve is work done.
