Question 22

What is kinetic energy?

Answer 22

A shot which dissipates its energy on impact and requires no triggering device

Question 23

What is reverse impact detonation?

Answer 23

Detonation occurs befor the fuze can detonate the fill. The shock wave will travel in the wrong direction

Question 24

Question 28

What factors affect frag performance?

Answer 28

Orientation Distribution Height of burst

Question 29

What is blast?

Answer 29

A violent disruptive effect caused by an explosion. There is an evolution of heat and gas which produces a shock wave from the center.
