What is explosion in physics definition?


Sharing is Caring


An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves.

What is an explosion in momentum?

Why is an explosion inelastic collision?

Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision.

What are the 3 types of collision?

Collisions are of three types: perfectly elastic collision. inelastic collision. perfectly inelastic collision.

What causes an explosion?

What Causes Explosions? An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions.

Is momentum conserved in an explosion collision?

Whether it is a collision or an explosion, if it occurs in an isolated system, then each object involved encounters the same impulse to cause the same momentum change. The impulse and momentum change on each object are equal in magnitude and opposite in direction. Thus, the total system momentum is conserved.

Does an explosion have kinetic energy?

Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly. So, like in inelastic collisions, total kinetic energy is not conserved in explosions.

What kind of energy is an explosion?

Yet all are instances in which flow energy first converts gradually to magnetic energy and then explosively dissipates into kinetic energy andโ€”in the case of flaresโ€”into electromagnetic radiation.

Why does kinetic energy increase in explosion?

The chemical energy of the shell is converted to mechanical energy. The external potential energy gets converted to its kinetic energy due to explosion. So kinetic energy increases.

What is difference between elastic and inelastic collision?

Collisions come in two main types ‘” elastic and inelastic collisions. An elastic collision is a collision where the colliding objects bounce back without undergoing any deformation or heat generation. An inelastic collision is a collision where the colliding objects are distorted and heat is generated.

What is explosive force?

The ability to use short bursts of muscle force to propel oneself (as in jumping or sprinting), or to throw an object. Level examples: Level.

What is meant by inelastic collision?

Definition of inelastic collision : a collision in which part of the kinetic energy of the colliding particles changes into another form of energy (such as heat or radiation)

What are the 2 types of collision?

There are two types of collisions: Inelastic collisions: momentum is conserved, Elastic collisions: momentum is conserved and kinetic energy is conserved.

What are two examples of collisions?

collision, also called impact, 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.

What are collisions explain its types?

Collisions are of two types : i) Elastic collision : The collision in which both momentum and kinetic energy is constant is called elastic collision. ii) Inelastic collision: The collision in which momentum remains constant but not kinetic energy is called Inelastic collision.

What is explosion Short answer?

An explosion is a rapid increase in volume and release of energy. in an extreme manner, usually with the generation of high temperature and the release of gases.

What are the types of explosion?

There are three main types of explosions: chemical, mechanical and nuclear. Each type of explosion can be equally devastating and serious, causing unprecedented harm to the surrounding people, atmosphere and infrastructure.

What are the effect of explosion?

Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering.

How do you calculate momentum explosion?

In which type of collision is momentum conserved?

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.

Is energy conserved in bomb explosion?

The chemical energy possessed by the bomb after explosion converts into heat energy, sound energy, light energy i.e. into different forms of energy but remains conserved. Hence, total energy of bomb does not change, but kinetic and mechanical energy changes.

What type of collision is an explosion?

An explosion is a special type of collision. It is a perfectly inelastic collision that seemingly happens in reverse. Before the ‘collision’, all objects are stuck together. After the ‘collision’, all objects are moving apart from one another.

What elements can cause explosions?

Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents.

Does kinetic energy increase after an explosion?

Thus, we see that, although the momentum of the system is conserved in an explosion, the kinetic energy of the system most definitely is not; it increases. This interactionโ€”one object becoming many, with an increase of kinetic energy of the systemโ€”is called an explosion. Where does the energy come from?

What energy changes occur during an explosion?

In an explosion, much of the potential energy stored in the chemical bonds of the explosive material is converted into kinetic energy of the gaseous products formed. (Other ambient gases, such as N2 in air, would also absorb that heat.)
