# Use the laws of conservation of momentum and energy to explain how a shape charge can direct most of the energy released in an explosion in a specific direction. (Note that this is similar to the situation in guns and cannons−most of the energy goes into the bullet.)

To determine

To Explain:

Most of the energy released in the explosion from shape charges in a specific direction.

Explanation

Introduction:

Conservation of momentum:

it states that if there is no external force acting on the system the total momentum remains constant.

Conservation of energy:

it states that energy can neither be created nor be destroyed. it can only transfer from one form to another form for an isolated system.

A shaped charge is an explosive charge. It is used to cut and form metal, initiate nuclear weapons, penetrate armor...
