1. When a soccer player kicks a soccer ball, which type of collision usually occurs? <br />A) It depends on how much heat is generated <br />B) More information is needed <br />C) Inelastic <br />D) Elastic <br />E) It depends on how much momentum is generated <br /> <br />2. How is it possible for momentum to be conserved in a system if the individual components experience a change? <br />A) The individual momenta are equal and opposite <br />B) The external forces are equal and opposite <br />C) All are correct <br />D) The individual masses are equal and opposite <br />E) The individual velocities are equal and opposite <br /> <br />3. What is a collision? <br />A) Two internal forces creating movement of an object <br />B) Two objects traveling away from each other <br />C) Two objects repelling each other <br />D) Two objects coming in contact with each other <br />E) Two external forces creating movement of an object <br /> <br />4. Why are perfectly elastic collision rare? <br />A) None are correct <br />B) Some heat is usually generated <br />C) Some permanent deformation always occurs <br />D) No heat is generated <br />E) Momentum can never really be conserved <br /> <br />5. Which best describes an elastic collision? <br />A) Heat is generated <br />B) Permanent damage occurs <br />C) Two objects have the same velocity <br />D) Two objects have the same momentum <br />E) No permanent damage occurs
