  2. collision, in physics, the sudden, forceful coming together in direct contact of two bodies, such as, for example, two billiard balls, a golf club and a ball, a hammer and a nail head, two railroad cars when being coupled together, or a falling object and a floor.

  3. In physics, a collision is an event in which two or more bodies exert forces on each other in a relatively short period of time. This interaction results in a change in the velocity and momentum of the colliding bodies.

    In physics, a collision is any event in which two or more bodies exert forces on each other in a relatively short time. Although the most common use of the word collision refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force.

  5. A collision is short duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity ). The magnitude of the velocity difference at impact is called the closing speed.

  6. Collision: When two bodies are approaching each other, a force comes into play between them for a finite time and brings about a measurable change in their velocities, momentum and energy according to the respective laws of conservation, a collision is said to have taken place.

  7. Jun 15, 2023 · Define the system to be the two particles. This is a collision, so we should first identify what kind. Since we are told the two particles form a single particle after the collision, this means that the collision is perfectly inelastic. Thus, kinetic energy is not conserved, but momentum is.

  8. Collision: When two bodies are approaching each other, a force comes into play between them for a finite time and brings about a measurable change in their velocities, momentum and energy according to the respective laws of conservation, a collision is said to have taken place.
