SUMMARY
The discussion centers on the existence of normal forces when two surfaces are in contact. A participant argues that a normal force can be zero, citing the example of a block in a freely falling lift, where the normal force between the block and the floor is indeed zero. Contrarily, a textbook, "The Pinnacle FIITJEE package for Newton's Laws," asserts that a normal force always exists without providing an explanation. This discrepancy raises questions about the interpretation of normal forces in different contexts.
