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.
Broadside collisions are where the side of one vehicle is impacted by the front or rear of another vehicle, forming a "T". In the United States and Canada this collision type is also known as a right-angle collision or T-bone collision; it is also sometimes referred to by the abbreviation "AABS" for "auto accident, broadside".

At normal speeds, during a perfectly inelastic collision, an object struck by a projectile will deform, and this deformation will absorb most or all of the force of the collision. Viewed from a conservation of energy perspective, the kinetic energy of the projectile is changed into heat and sound energy, as a result of the deformations and ...
After head-on collisions, the most common severe injury accident is the side impact. WorldSID is an advanced side impact ATD, used for EuroNCAP side impact test modes. The SID (Side Impact Dummy) family of test dummies is designed to measure rib, spine, and internal organ effects in side collisions. It also assesses spine and rib deceleration ...
The left-hand side is the time derivative of the momentum, and the right-hand side is the force, represented in terms of the potential energy. [9]: 737 Landau and Lifshitz argue that the Lagrangian formulation makes the conceptual content of classical mechanics more clear than starting with Newton's laws. [26]
In particle physics, underlying event (UE) refers to the additional interactions of two particle beams at a collision point beyond the main collision under study. . Specifically, the term is used for hadron collider events which do not originate from the primary hard scattering (high energy, high momentum impact)
A collider is a type of particle accelerator that brings two opposing particle beams together such that the particles collide. [1] Compared to other particle accelerators in which the moving particles collide with a stationary matter target, colliders can achieve higher collision energies.
In physics, an elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat , noise, or potential energy .
