    Model Railgun Project - Don't have a grasp of the physics

    Please disregard what I stated previously. A railgun can achieve very high muzzle velocities because of the constant acceleration that is achieved. Meaning, that, the longer the barrel, the higher the muzzle velocity will be. If you were looking for a few formulas : F = ma ; F ->...

    Railgun Math Simulator: Build Your Own | 400km/h Launch Projectile

    Hey all Im a second year engineering student bored as hell in the second week of a 3 month vacation. So i decided to try and build a small railgun capable of launching a projectile(20-40g) to about 400km/h. Attached is a excel file. It is a sort of simulation. Cells in Blue must be typed...

    2nd year Eng.student trying to build a railgun. Verify or modify please

    Kind of forgot about the user friendliness. The gun will make use of a capasitor bank. The capasitance and voltage of each of the caps can be set manually. The resistance is in a column. It seems very low, but it is assumed that between 3-6 caps are used in parrallel.

    Hey all Im trying to build a small railgun capable of launching a projectile(20-40g) to about 400km/h. Attached is a excel file. It is a sort of simulation. Cells in red must get values from the table. Cells in Blue must be typed in by user. Cells in Green list the Current/Mass needed...

    Electromagnetic Railgun - calculations

    Try this site, seems very legit. http://www.powerlabs.org/railgun2.htm Im trying to build one myself, but much smaller than the one in the link. Thinking 400-500 km/h muzzle velocity. seems very achievable Good luck hope this helped

    Model Railgun Project - Don't have a grasp of the physics

    I don't know if this still works for railguns...but F= ma, get a. then vf^2 = vi^2 + 2ax vf = final velocity vi = initial velocity x = rail length And to answer your question, a higher vf will surely increase the distance the projectile travels.
