Q:Q: The force exerted by a diving board is conservative, provided the internal friction is this? Read this paragraph and choose the correct option from the provided answers: 7.4 Conservative Forces and Potential Energy 9. What is a conservative force? 10. The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it. Define mechanical energy. What is the relationship of mechanical energy to nonconservative forces? What happens to mechanical energy if only conservative forces act? 12. What is the relationship of potential energy to conservative force?. Choices: - static - intrinsic - significant - negligible A:
A:
negligible
