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.

What is the equation for the work done by the force of gravity?

Explain why the force of gravity does zero work on the block on a level surface.

How does the angle between the force of gravity and the displacement of the block change on the incline?

Describe the relationship between the incline angle and the angle used in the work done by gravity equation.

What is the calculated work done by the force of gravity as the block slides from compressing the spring to its maximum height on the incline?
