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 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.


The three stages of a collision include?

There are three stages of a collision. These include the vehicle collision, the human collision, as well as the internal collision.

What is elastic collistion?

Elastic collision is a type of collision whereby the total kinetic energy of the various bodies involved in collision after the collision, equals their total kinetic energy right before the 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.

A 500 kg truck moving at 30 ms strikes a parked 300 kg car they connect and move together what kind of collision is this?

It is a perfectly inelastic collision.Types of collisions:* Perfectly inelastic- collision in which two objects stick together after the collision so that their final velocities are the same. * Elastic-collision in which the two objects bounce after the collision so that they move separately * Inelastic-collision in which the two objects deform during the collision so that the total kinetic energy decreases , but the objects move separately after the collision.
