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.

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.

Explore the concept of collisions in physics, including definitions, types (elastic and inelastic), and practical examples. Understand the dynamics of how objects interact and transfer energy during collisions.

A traffic collision in Japan, 2007 The aftermath of an accident involving a jackknifing truck, Mozambique, Africa. A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. . Traffic collisions often result …

This collection of interactive simulations allow learners of Physics to explore core physics concepts by altering variables and observing the results. This section contains nearly 100 simulations and the numbers continue to grow.

A collision is when two objects impact each other over a short space of time. The momentum of each object can change, but the total momentum does not. We say the momentum is conserved (the total stays the same). Conserved: the total stays the same (within a closed system).

Although momentum is conserved in all interactions, not all interactions (collisions or explosions) are the same. The possibilities include: A single object can explode into multiple objects (explosions). Multiple objects can collide and stick together, forming a single object (inelastic).

A collision occurs when two objects come in direct contact. It is the event in which two or more bodies exert forces on each other in about a relatively short time. There are two types of collisions, namely: Elastic Collision. An elastic collision is one where there is no net loss in kinetic energy in the system due to the collision. Inelastic ...
