When a bomb explodes in mid air at the highest point what is the direction of motion of its core?

When a bomb explodes in mid air, at its highest point, what is the direction of motion of its core? Dear student, At the highest position as the bomb has zero velocity, so it is momentarily at rest. Therefore to conserve the momentum the two fragments will fly off in two opposite directions.

Why momentum is conserved in bomb explosion?

UPDATE : The explosion itself conserves linear momentum, regardless of how small the fragments are. If we ignore gravity and air resistance and all other external forces, there is no change in total momentum. This is because the internal forces all occur in equal and opposite pairs (Newton’s 3rd Law).

Is kinetic energy conserved in an explosion?

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.

How energy is conserved in an explosion?

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. But total momentum is always conserved.

Are explosions endothermic?

The issue of whether a reaction is endothermic or exothermic is important in the forensic investigation of explosions. The explosion of an endothermic substance is in itself exothermic, with the chemical potential energy of the compound being released in the form of heat, light, and sound.

What affects momentum conservation?

The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton’s laws of motion. Momentum is conserved in all three physical directions at the same time.

How is momentum related to the effects or damages due to vehicular collision?

As mentioned above, if cars rebound upon collision, the momentum change will be larger and so will the impulse. A greater impulse will typically be associated with a bigger force. Occupants of automobiles would certainly prefer small forces upon their bodies during collisions.

What is conserved in an explosion?

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.

Is a bomb exploding endothermic or exothermic?

off in a reaction is primarily in the form of heat, the reaction is called an exothermic reaction. and the explosion of dynamite are exothermic reactions.

Is a bomb exploding an exothermic reaction?

Explosives as we know them are exothermic: they produce heat and light, or, in other words, energy is expelled. Let’s consider endothermic bombs: weapons that, upon detonation, consume heat and / or light and / or nearby electricity.

How is the resulting change in momentum affected?

How is the resulting change in momentum affected? Momentum is doubled. Force of impact is one-quarter (1/4). Impulse is an action / reaction / force that causes a change in momentum.
