If 0 < K f < K i, the collision is inelastic. If K f = 0 , the collision is perfectly inelastic. If K f = K i, the collision is elastic. If K f > K i, the interaction is an explosion. The point of all this is that, in analyzing a collision or explosion, you can use both momentum and kinetic energy.

15 cze 2023 · An elastic collision is one that conserves kinetic energy. An inelastic collision does not conserve kinetic energy. Momentum is conserved regardless of whether or not kinetic energy is conserved. …
The possibilities include: A single object can explode into multiple objects (one-to-many). Multiple objects can collide and stick together, forming a single object (many-to-one). Multiple objects can collide and bounce off of each other, remaining as multiple objects (many-to-many).
5 lip 2022 · A collision (or explosion) is either: Elastic – if the kinetic energy is conserved. Inelastic – if the kinetic energy is not conserved. Collisions are when objects strike against each other. Elastic collisions are commonly those where objects colliding do not stick together and then move in opposite directions.
Interactions between molecules are examples of perfectly elastic collisions. In most other cases (eg snooker balls), collisions are not perfectly elastic - some kinetic energy is lost.
Analyzing a Car Crash At a stoplight, a large truck (3000 kg) collides with a motionless small car (1200 kg). The truck comes to an instantaneous stop; the car slides straight ahead, coming to a stop after sliding 10 meters. The measured coefficient of friction between the car’s tires and the road was 0.62.
