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 would two masses before a collision is 100kg what is the total momentum after they collied?

The total momentum before a collision is equal to the total momentum after the collision, according to the law of conservation of momentum. If the two masses have a combined mass of 100 kg before the collision, their total momentum before the collision will depend on their velocities at that moment. After the collision, assuming no external forces act on the system, the total momentum will remain the same as it was before the collision. Thus, the total momentum after the collision will also be equal to the total momentum before the collision.


During the interval of collision is the momentum conserved?

In an isolated system where no external forces are acting, momentum is conserved during the interval of collision. This means the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.


What color light to prevent a collision?

Any color light can prevent a collision.


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.


When will a collision lead to a chemical reaction?

When the collision is hard and fast enough. Increasing the kinetic energy will increase the likelihood of hard and fast collisions, which will ultimately increase the rate of the reaction. (This is called collision theory.)

What does elastic collision mean?

In an elastic collision, both kinetic energy and momentum are conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision, and the total momentum before the collision is equal to the total momentum after the collision.


What collision has no energy loss?

An elastic collision is a type of collision in which there is no net loss in kinetic energy. In an elastic collision, both momentum and kinetic energy are conserved. This means that the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision.

Is momentum conserved in an elastic collision?

Yes, momentum is conserved in an elastic collision, meaning the total momentum of the system before the collision is equal to the total momentum after the collision.


How can one determine the momentum after a collision?

To determine the momentum after a collision, you can use the principle of conservation of momentum. This principle states that the total momentum before a collision is equal to the total momentum after the collision. By calculating the initial momentum of the objects involved in the collision and applying this principle, you can find the momentum after the collision.
