SUMMARY
The discussion focuses on calculating the work done by gravitational force on a box being pushed up a frictionless incline. The box has a mass of 5 kg and is pushed a distance of 13 m at an incline of 34°. The correct formula for gravitational work is Wg = mgh, where h is the height calculated using h = d * sin(q). The participant initially calculated Wg as 358.1 J but later realized that the work done by gravity is negative, indicating that gravitational work opposes the motion.
