Work due to the Force of Gravity on an Incline by Billy

Billy presents a video on the work equation, focusing on the work done by gravity as a block moves from compressing a spring to its maximum height on an incline. The video is a continuation of a previous one and explains how to calculate the work done by gravity on both level and inclined surfaces. The analysis involves understanding the angles between the force of gravity and displacement, and calculating the work done using these angles. The video concludes with a calculation of the work done by gravity, resulting in -4.4 millijoules.
