In an Inelastic collision the 2 object ______

• stick together

• bounce off one another

• stretch one another

• break 1 or both objects

Velocity is not the same for both objects after _______ collision.

Recall: The smaller object will have to have a greater speed than the larger in order to have the same momentum.

Kinetic energy is perfectly conserved in _____ collisions.

• Elastic

• Inelastic

• Both

• Neither

Damage does not occur in _____ collisions, which is why KE is conserved. All the energy is kept as motion (aka mechanical energy)

• Elastic

• Inelastic

• Both

• Neither

Damage DOES occur in _____ collisions, which is why KE is transfered

• Elastic

• Inelastic

• Both

• Neither

Some Kinetic energy is transferred in _____ collisions into heat, light, and sound, because DAMAGE DOES HAPPEN this transfers the motion/mechanical energy to other forms.

• Elastic

• Inelastic

• Both

• Neither
