Lesson 4 Inelastic vs. Elastic Collision Quiz

Which best describes an elastic collision?

• Permanent damage occurs

• Heat is generated

• No permanent damage occurs

• Two objects have the same velocity

What is a collision?

• Two external forces creating movement of an object

• Two objects traveling away from each other

• Two objects repelling each other

• Two internal forces creating movement of an object

• Two objects coming in contact with each other

When a soccer player kicks a soccer ball, which type of collision usually occurs?

• Inelastic

• Elastic

• It depends on how much momentum is generated

• More information is needed

• It depends on how much heat is generated

How is it possible for momentum to be conserved in a system if the momentum of the individual components experience a change?

• The individual masses are equal and opposite

• The change in individual momenta are equal and opposite

• The external forces are equal and opposite

• All are correct

• The individual velocities are equal and opposite

Why are perfectly elastic collisions rare?

(Choose 2)

• Some heat is usually generated

• None are correct

• No heat is generated

• Some permanent deformation always occurs

• Momentum can never really be conserved
