Question: In a perfectly inelastic collision, what happens to the kinetic energy of the system?

Options:

  1. It is conserved
  2. It is lost
  3. It is doubled
  4. It is halved

Correct Answer: It is lost

Solution: 

In a perfectly inelastic collision, the two colliding objects stick together, and some kinetic energy is transformed into other forms of energy, resulting in a loss of kinetic energy.

Questions & Step-by-Step Solutions

In a perfectly inelastic collision, what happens to the kinetic energy of the system?
  • Step 1: Understand what a perfectly inelastic collision is. In this type of collision, two objects collide and stick together after the collision.
  • Step 2: Recognize that before the collision, both objects have kinetic energy due to their motion.
  • Step 3: When the objects collide and stick together, they move as one combined object.
  • Step 4: Realize that during the collision, some of the kinetic energy is transformed into other forms of energy, like heat or sound.
  • Step 5: Conclude that because some kinetic energy is transformed, the total kinetic energy of the system after the collision is less than it was before the collision.
  • Perfectly Inelastic Collision – A type of collision where two objects collide and stick together, moving as a single object post-collision.
  • Kinetic Energy Transformation – In a perfectly inelastic collision, some kinetic energy is converted into other forms of energy, such as heat or sound.
