Practice question · Put in order
Order the stages of a perfectly inelastic collision between two objects.
- Kinetic energy has decreased (converted to heat/deformation)
- Objects make contact
- Combined object moves with shared velocity
- Two objects approach each other
- Objects deform and stick together
Hints
- Momentum is conserved through the impact itself.
- Perfectly inelastic means the two leave with a single common velocity.
Show the answer
- Two objects approach each other
- Objects make contact
- Objects deform and stick together
- Combined object moves with shared velocity
- Kinetic energy has decreased (converted to heat/deformation)
Why
In perfectly inelastic collisions, objects stick together and KE is lost.
