Example: A 0.75kg baseball moving at 30m/s left encounters a bat exerting 900N of force for 0.5s, resulting in a final velocity calculation.

Definition: Elastic collisions maintain kinetic energy, while inelastic collisions involve energy losses to friction, heat, or sound.

Highlight: Elastic collisions occur in environments with minimal friction, such as ice surfaces or space.

Example: Air hockey tables demonstrate elastic collisions, while car crashes exemplify inelastic collisions.

Example: A 500kg car traveling at 30m/s collides with a 600kg car moving at 20m/s, resulting in an inelastic collision with a final velocity of 24.5m/s.

Highlight: The solution process demonstrates how to apply conservation of momentum equations in real-world scenarios.

Example: A 3000kg truck colliding with a 1000kg parked car illustrates elastic collision calculations, showing how to determine final velocities of both vehicles.

Definition: In inelastic collisions, objects stick together after impact, sharing a common final velocity.

Definition: Momentum (P) is the product of an object's mass and velocity, expressed as P=mv.

Vocabulary: Impulse (J) represents the change in momentum, calculated using the formula J=Ft.

Highlight: The units for both impulse and momentum are identical, measured in Newton-seconds (Ns) or kilogram-meters per second $kgm/s$.

Example: The impulse-momentum theorem shows that Ft = m$vf-vi$, connecting force and time to mass and velocity changes.
