The discussion clarifies the concept of weightlessness during freefall, emphasizing that while in the air, an individual experiences zero normal force, leading to the sensation of weightlessness. The equation W=mg remains valid, as weight (W) is defined as the product of mass (m) and gravitational acceleration (g), which do not change. When jumping from an airplane, the scale reads zero due to the absence of the normal force (N) acting upward, confirming that the only force present is the gravitational force pulling downward.
PREREQUISITESStudents of physics, educators teaching concepts of motion and forces, and anyone interested in understanding the principles of weightlessness and freefall dynamics.
am i missing something?
