    How Much Thrust Does a 1W Flashlight Emit?

    well I can garentee you I'll never be asking about any homeworks. I only ask for personal interest. That's the reason for my simple numbers, because it's just a question i randomly made up. it's not like I'm trying to make anyone to work for me or anything like that. so you see if I didn't...

    How Much Thrust Does a 1W Flashlight Emit?

    What would be the thrust from a 1W light output flashlight, assuming light is not scatered at all. I'm not sure but if it depends on the wavelength, assume it only emits 500nm light. and if I were to put a perfect mirror right infront of this flashlight would the mirror receive the same...

    Wired question request some pro help

    Thanks, I thought so... But the problem remains, without a super mind-blowing and eye catching list of equations, my reputations remains as knowing nothing about physics and ignores the laws of gravity, escape velocity and so on and so forth... So, how can I convince people that I'm right about...

    Wired question request some pro help

    I have a question that is not present in any physics book I've ever seen: Supose I have a rocket with infinite fuel, but it's mass is constant. This rocket's power is limited and can only provide enugh thrust to accelerate it self at a rate of just over 9.81M/s. If I were to lunch this rocket...
