on a collision courseOf a person, group, or object, on a certain path to conflict, collision, destruction, or ruin with someone or something else. The radical left-wing coalition is set to be on a collision course with the majority conservative government this January. Little did the passengers know that they were riding a train on a collision course with disaster.See also: collision, course, onbe on a collision courseOf a person, group, or object, to be on a certain path to conflict, collision, destruction, or ruin with someone or something else.

collision Physics an event in which two or more bodies or particles come together with a resulting change of direction and, normally, energy Collision (physics) Any interaction between particles, aggregates of particles, or rigid bodies in which they come near enough to exert a mutual influence, generally with exchange of energy. The term collision, as used in physics, does not necessarily imply actual contact. In classical mechanics, collision problems are concerned with the relation of the magnitudes and directions of the velocities of colliding bodies after collision to the velocity vectors of the bodies before collision. When the only forces on the colliding bodies are those exerted by the bodies themselves, the principle of conservation of momentum states that the total momentum of the system is unchanged in the collision process. This result is particularly useful when the forces between the colliding bodies act only during the instant of collision. The velocities can then change only during the collision process, which takes place in a short time interval. Under these conditions the forces can be treated as impulsive forces, the effects of which can be expressed in terms of an experimental parameter known as the coefficient of restitution. See Conservation of momentum, Impact The study of collisions of molecules, atoms, and nuclear particles is an important field of physics. Here the object is usually to obtain information about the forces acting between the particles. The velocities of the particles are measured before and after collision. Although quantum mechanics instead of classical mechanics should be used to describe the motion of the particles, many of the conclusions of classical collision theory are valid. See Scattering experiments (atoms and molecules), Scattering experiments (nuclei) Collisions can be classed as elastic and inelastic. In an elastic collision, mechanical energy is conserved; that is, the total kinetic energy of the system of particles after collision equals the total kinetic energy before collision. For inelastic collisions, however, the total kinetic energy after collision is different from the initial total kinetic energy. In classical mechanics the total mechanical energy after an inelastic collision is ordinarily less than the initial total mechanical energy, and the mechanical energy which is lost is converted into heat. However, an inelastic collision in which the total energy after collision is greater than the initial total energy sometimes can occur in classical mechanics. For example, a collision can cause an explosion which converts chemical energy into mechanical energy. In molecular, atomic, and nuclear systems, which are governed by quantum mechanics, the energy levels of the particles can be changed during collisions. Thus these inelastic collisions can involve either a gain or a loss in mechanical energy. collision[kə′lizh·ən] (physics) An interaction resulting from the close approach of two or more bodies, particles, or systems of particles, and confined to a relatively short time interval during which the motion of at least one of the particles or systems changes abruptly. collision (networking)When two hosts transmit on a network atonce causing their packets to corrupt each other.

Related to Collision: elastic collision, Collision theoryCollisionThe violent contact of one vehicle—such as an automobile, ship, or boat—with another vehicle. Collision insurance is a type of policy that motorists purchase to cover property losses in the event of a car accident. A collision that does not result from the Negligence of either vessel involved is considered to be an inevitable accident. In the event of an inevitable accident, neither party is liable to the other, but each bears his or her own individual losses. Exclusion from fault is ordinarily determined with reference to the safeguards observed by the parties to the inevitable accident. COLLISION, maritime law. It takes place when two ships or other vessels run foul of each other, or when one runs foul of the other. In such cases there is almost. always a damage incurred.
2. There are four possibilities under which an accident of this sort may occur. 1. It may happen without blame being imputable to either party, as when the loss is occasioned by a storm, or any other vis major; in that case the loss must be borne by the party on whom it happens to light, the other not being responsible to him in, any degree.
3. - 2. Both parties may be to blame, as when there has been a want of due diligence or of skill on both sides; in such cases, the loss must be apportioned between them, as having been occasioned by the fault of both of them. 6 Whart. R. 311..
4. - 3. The suffering party may have been the cause of the injury, then he must bear the loss.
5. - 4. It may have been the fault of the ship which ran down the other; in this case the injured party would be entitled to an entire compensation from the other. 2 Dodson's Rep. 83, 85; 3 Hagg. Adm. R. 320; 1 How. S. C. R. 89. The same rule is applied to steamers.. Id. 414.
6. - 5. Another case has been put, namely, when there has been some fault or neglect, but on which side the blame lies, is uncertain. In this case, it does not appear to be settled whether the loss shall be apportioned or borne by the suffering party opinions on this subject are divided.
7. A collision between two ships on the high seas, whether it be the result of accident or negligence, is, in all cases, to be deemed a peril of the seas within the meaning of a policy of insurance. 2 Story, R. 176; 3 Sumn.
