piston weight

[ian118118 10]

what is the point in having a piston weight in a air rifle, the only thing i can think of isit decreases power because it is adding weight to the piston when it moves, but theremust be something else?

Just because something is heavier doesnt mean it has less power....think about it..flyweight boxer, moves his arms very fast when punching, the weight of the punch doesnt carry a massive amount of energy even though it travels fast. Heavy weight boxer, the speed of the punch is much slower but boy does the impact carry some weight.

 

Now apply this to the piston weight at the end of a compressed spring.

 

Its a carefully chosen piston weight based on the following:

 

Kinetic energy = 0.5 mass x velocity2

force = mass x aceleration

Pressure = force / area

well explained that man!
