nobody here understands Newton's Second law. This makes me sad for humanity.
edit: i'll break it down for you.
kinetic energy is mass * velocity. (.5mv^2 to be exact)
Velocity is the differential of acceleration to time.
Acceleration to an object in the vacuum of space is constant unless a force acts upon it (this would be gravity, thrusters, another object colliding etc). Unlike the previous post, velocity is not constant, acceleration is.
So the longer my projectile is in space the higher the velocity is. Since the velocity is going to increase at the same acceleration for as long as it doesn't collide with something, the kinetic energy will increase.
A projectile weapon like a cannon should have it's weakest damage at point blank range. It's highest damage at whatever the furthest distance the game will register an impact (4km seems to be the upper limit). While it may be unreasonable to ask the game engine to render correct kinematic physics like ever increasing velocity of projectiles, it would be trivial to modify the damage the same way (but inversely) as it's done for energy weapons.
Sorry man. Just no. The way you describe it completely violates the law of conservation of energy.
Energy can neither be created nor destroyed, only transferred.
You've got it all wrong. Otherwise, e=mc^2 doesn't hold up and any spacecraft can reach the speed of light through a simple energy input from a stationary point of launch and require no subsequent sustained input to eventually reach C. I can assure this is NOT POSSIBLE.
The moment you remove an accelerative force to an object, be it in space, gravity field, atmosphere--whatever it may be, the acceleration immediately stops. The velocity will remain constant in space from there on out until it is acted upon by another object or force.
I'm sorry, I don't make this up. These are the laws of physics. If you'd like to dispute me, fine. But before you do, PLEASE read a few books on Newtonian physics first.
This is why we can't reach Mars in a matter of days with a simple booster engine that thrusts for a few minutes and ultimately accelerate to super high velocities. This is why probes to Mars, Jupiter, Saturn and even things such as comets have to slingshot around planets to build velocity.
*sigh*
You really believe you're right. But you aren't. You've got it so wrong it isn't even funny.
A projectile weapon has force applied to it at the point the cartridge/detonation source imparts its energy into it. Once this is done, there are no more accelerative forces imparted to. There is no energy being created beyond that point. If the projectile were to continue to accelerate beyond this initial phase, you would have perpetual creation of energy thus violating not only the law of conservation of energy but the entire entropy of the universe given time.
I'm getting ticked off just typing this post. Go back to school please.
