Label the diagram of an inelastic collision.
Objects stick together after the collision, kinetic energy is not conserved.
Label the diagram of an elastic collision.
Objects bounce off each other, both kinetic energy and momentum are conserved.
What are the differences between elastic and inelastic collisions?
Elastic: Both momentum and kinetic energy are conserved. Inelastic: Momentum is conserved, but kinetic energy is not.
What is momentum?
Momentum is usually conserved during a collision if the net external force on a system is zero (or negligible).
What is an elastic collision?
A collision where objects bounce off each other, and both momentum and kinetic energy are conserved.
What is an inelastic collision?
A collision where objects either stick together or deform, and kinetic energy is not conserved, but momentum is still conserved.
What is a completely inelastic collision?
A special type of inelastic collision where objects stick together after colliding.
What is the center of mass (COM)?
The point where the system's mass is evenly distributed; the balancing point of an object.
