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.
