If you use a lower pressure you will actually lose velocity. Think about this. Pressure is force over an area correct? So if you keep your area the same, the firing chamber, and the force decreases if the pressure decreases. So what is going on is that you are pushing your paintball with a lower...
I am trying to get the coeficient gamma=1/squareroot(1-(v/c)2)
I am trying to do this by my own knowledge starting from scratch.
Can someone give me the first step? I want to see if i can get there but i just need a hint i am not sure on where to start
Thankyou very much,

I have finally understood you. I will discuss the forces later on. To start you have said "The BoatS move apart" That is to say two boats. The explosion that creats 1million J is used to move those TWO boats not one. There fore they will both have 500k J. So you have spent 1 million J to move...
I never debated that. I am debating the fact that you just said Newtons Law, which is where the law of conservation of energy comes from, is wrong. And you do have to take into acount the forces because that's what makes everything move.
Okay. Let's go step by step. You stationary on the...
So what you are saying is that yes you push/apply a force on the boat. The boat logically moves away. If the boat doesn't push back how is your boat moving? In your terms there has been no force on your boat. There for there should not be any change in your velocity. There for your boat should...
You do? What happened to Newtons law? Did it fly out the window? haha You must remember that when you apply a force on an object it pushes back on you. This is the part that i see you must have trouble with. The object(whatever it is boat rock) will always push back. Therefore doing work on you...
see but you did not invest 20 joules. Us two pushing on each other added up to 20 joules. If you pushed 100N for .1meters then the you have invested 10 joules there, for you to invest 20 you would have to double either your distance you pushed or the force you pushed
The energy you are investing is 10 joules correct? That is to say that you pushed 100N for .1meters. That is how much you have personally invested. You have now pushed the boat which has 10 joules of energy. Your boat will also have 10 joules of energy. So you will invest 10 joules, your boat...
Okay first: I know i was thinking the same thing with the investments hahaha.
Your so called investment which is the total work by pushing you did went into my boat moving. While when you were pushing on my boat the boat was pushing back and so my boats investment went into your body which is...
Ahhhhh See now i understand what you want me to answer,
Your boat will yes have half of the energy of the SYSTEM but not on what you have invested. If you concsider a coordinate system where your forward is positive and your backwards is negative, The you push on my boat in the negative...
Actually it might depend on how you push off. When you push off like i explained earlier as in 100N for .1 meters you will have the same kinetic energy for both but you will have different momentums. At least that is what i calculated out and the physics seems to check out.

Well you have to understand the Plancks fromula is for photons. Where as Newtons formula is for objects. Next part is that yes velocity is the most determining factor in Newtons law but Photon travel at the speed of light which is constant. It does not ever change even if its doppler shifted...
Lets begin by saying we are in deep space. No gravity nothing. You push off from a rock the same mass as you. You exert a force of 100N for .1meters. You have done 10 Joules of work. Now let's look at the after math. The Rock has also done 10 Joules but in the opposite direction. To make things...
This applies to both kinetic and static friction, Kinetic friction is μ*mg and static is the same thing. The only difference is that the 'μ' will be a different value. Also Kinetic friction is less than Static friction, it wouldn't make sense that Kinetic be more, this would mean that if the...
