How does electricity have anything to do with stopping power?


"Oh yeah, I have my scuba kit because it's resistant to fire."

Graphene has many unique properties, making it an ideal material for use in bulletproof vest.
1):It has very high thermal resistance.Very high melting and boiling point which helps against the heat which is generated by the velocity of the bullet
2): Graphene is known to be one of the strongest materials ever made and a single-layer graphene sheet can withstand up to 42 N m-1 of STRESS and GREAT FORCE (Impulse/momentum), with a Young’s modulus of 1.0 Tpa. which is very useful.
3):It is incredibly light yet so strong for its weight so it is easier to carry then some vest if they were made of for e.g lead xD.
4):Graphene withstands 10 times the kinetic energy then steel can

I got A in Igcse
