Questions & Step-by-Step Solutions
Which of the following statements is true about a perfectly inelastic collision?
Step 1: Understand what a collision is. A collision happens when two objects hit each other.
Step 2: Learn about different types of collisions. There are elastic collisions, inelastic collisions, and perfectly inelastic collisions.
Step 3: Know that in a perfectly inelastic collision, the two objects stick together after they collide.
Step 4: Remember that momentum is a measure of motion and is always conserved in collisions. This means the total momentum before the collision equals the total momentum after the collision.
Step 5: Understand that kinetic energy is the energy of motion. In a perfectly inelastic collision, some kinetic energy is lost because the objects stick together.
Step 6: Conclude that in a perfectly inelastic collision, momentum is conserved, but kinetic energy is not.
