SUMMARY
The discussion revolves around true and false questions related to kinetic energy and work. The first statement, "If there is no work there is no kinetic energy," is deemed false. The second statement, "There has to be a change in velocity for there to be a change in kinetic energy," is confirmed as true. The third statement, regarding the relevance of position above the Earth in gravitational contexts, is also marked false. The final assertion about the sum of kinetic energy and total energy equating to total work is not directly addressed in the answers provided.
