Question
Define scalar quantities and vector quantities. How do you distinguish them? What are the differences? Are they added or subtracted the same way? Explain. Show simple graphical representations of A + B and A - B (A and B are completely different vectors). Define an elastic collision, and state its important characteristics. Which energies are conserved during an elastic collision (i.e. kinetic energy, total energy, or both)? Define what an inelastic collision is, clearly stating its essential properties. Which physical quantities are conserved during an inelastic collision? Define a perfectly inelastic collision, and denote its defining characteristics. Which physical quantities are conserved during a perfectly inelastic collision? Identify whether the following quantities are scalars or vectors, and which of these are always conserved: (1) velocity; (2) speed; (3) momentum; (4) total momentum; (5) kinetic energy; (6) potential energy; and (7) total energy.Explanation / Answer
