A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time.
Although the most common colloquial use of the word "collision" refers to accidents in which two or more objects collide, the scientific use of the word "collision" implies nothing about the magnitude of the forces.
Types of collisionsA perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. In reality, any macroscopic collision between objects will convert some kinetic energy to internal energy and other forms of energy, so no large scale impacts are perfectly elastic. However, some problems are sufficiently close to perfectly elastic that they can be approximated as such.An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Momentum is conserved in inelastic collisions (as it is for elastic collisions), but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.
Collisions in ideal gases approach perfectly elastic collisions, as do scattering interactions of sub-atomic particles which are deflected by the electromagnetic force. Some large-scale interactions like the slingshot type gravitational interactions between satellites and planets are perfectly elastic.
Collisions between hard spheres may be nearly elastic, so it is useful to calculate the limiting case of an elastic collision. The assumption of conservation of momentum as well as the conservation of kinetic energy makes possible the calculation of the final velocities in two-body collisions.

What is glancing collision?
A collision where the velocity remains the same but there is impact still.
What color light to prevent a collision?
Any color light can prevent a collision.
During the interval of collision is the momentum conserved?
well i know momentum remains same before and after collision... But what about the period during which collision takes place?
How is momentum conserved after a collision?
Completely If you add all the energy of all the resultants of the collision together, you will arrive at the same value as the sum of the energies of all the components before the collision.
A baseball flies through an open window and collides with a vase The momentum of the ball and vase after the collision is?
A baseball flies through an open window and collides with a vase. The momentum of the ball and vase after the collision is the same as the momentum of the ball alone before the collision.
Second collision occurs when?
After the first collision.
What is the term given to the noise from the collision of stones?
Collision of the debris is the term that is given to the collision of the stones.
Collision in a sentence?
After a collision with another player, Greg had a concussion.She quickly swerved to the left to avoid a collision.
What is collision repair?
Repairing damage caused by a collision.
What part of speech is collision?
Collision is a noun.
How do routers and switches separate collision domains?
in my opinion there is no any collision domain in the router......but switch has collision domains for each interfaces & hub has one collision domain
What is the difference between an elastic collision and an inelastic collision?
No loss in energy due to collision is for elastic collision. But there will be a loss during collision in case of in-elastic collision. So KE will remain constant before and after collision in case of elastic collision.
What is a secondary collision?
When a vehicle is in a car accident there can be a secondary collision. For example, if car ÒbÓ was rear ended that is the first collision but when that car hit the car in front of them that is the secondary collision.
What is chargeable collision?
Chargeable Collision: A collision in which the actions of the driver of a City-owned vehicle are the primary cause of the collision. Normally, the driver will have violated state or local traffic law.
What does collision coverage automobile insurance cover?
Collision covers if you hit something or turn the vehicle over. The exception is an animal collision which is covered by comprehensive or (other than collision).
What is elastic and inelastic collision?
In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
Can you have a sentence with the word collision in it?
Did you hear about the collision yesterday in the park?
