@kaa3164 theres been a popularisation of science on tv recently. With brian cox this guy, and genius of britian . And hawkins brave new world .Its gaining prime time spots and people are loving it .Which is good to hear!
We'll see if that will not speed things up. And knowing there's a big reward for discoveries :). To me it's just wrong to receive funding for their research and at the same time to be rewarded per discovery. Their job should be treated as how regular jobs are treated. Pay them by the hour with deadlines and knowing they can be fired if they slack off.
I remember watching a science show where this guy discovered something and received 1mil after from an association (and he gave some to his colleagues) . That story was every bit right. Because it makes them race to the finish line. But to be funded for their research and experiments is a waste of time and money. Because it covers their meals, electricity and so many things. Now making it officially a full time responsibility in life. Place them in labs and pay them by the hour instead.
Because without work is without money. And patience for discoveries does not put food on the table on time. They would go for funding more than discovery rewards because it all comes down to responsibilities in life. But they get funded for their research plus a handsome reward per discovery. They should be hired per hour and not even be put on salary.
The calculation was for energy power +- after all. As our eyes didn't deceive us here, A projectile did occur here. The object was jetting upward by force. But it's losing energy from the gravity pull from the beginning and from the force fighting the gravity pull. That is where the declining is. I think they just want to make something sound impressive yet, slowing down the attempt for discoveries on time
the string theory i'm meaning being the one that relates to higher dimensional topology - eg, in terms of what stars came from what other stars, and from perhaps galactic center blackholes, then the theories would be able to describe how those remain linked to one another non-locally.
@MrLamaj123 - isn't gravity just what happens when - at an atomic scale - atoms aggregate together, so if many aggregate together they have a greater pull on any other atoms that may pass nearby them, and obviously in terms of atoms forming in the first place it'd play a similar role as a force. i think string theory will be useful when they realise all that hidden energy (dark-etc) is to do with higher dimensions, how this whole thing is packed together
i wonder if anyone has a link for this for example - a step-by-step of the process a calculator goes through with the number you give it, when it calculates a square root (and what is it told to do when you give it -1 - just display E?). and a link for the human-arithmetic step-by-step in square root caluclation also.
how do you actually get a square root of something you cannot calculate a square root of though. i know the whole complex number radiowaves turning at 90-degree-angle thing works in calculations - but the part where they figured out proofs of the square root of minus 1........which was long before computers of course....as is most proof of fundamental accepted things in maths, which aren't taught properly so you can see how they are calulcated....
What's so interesting about gravity is that it seems to be a much weaker force compared to say, electro-magnetism. But, if String Theory is correct, it may be possible, that gravity may be fading out of our membrane and into another one, therefore it could be equal or greater.
What is this guy talking about? If the projectile was never accelerating upwards, then it would not have been thrown up into the air. Instead, it would be stable. It IS accelerating because the trebuchet put energy into catapulting the projectile and thus defying gravity for a few moments.
@Vaylemn He says it's accelerating downwards *from the moment it leaves the trebuchet*. The treb puts the projectile into motion, but once they break contact, the projectile doesn't accelerate upwards at any point after that.
When the fireball leaves the trebuchet, it's still accelerating. The trebuchet put enough energy into the ball to keep it accelerating, giving the arc of the ball. You can check this with math - take the derivative for half the distance the ball traveled (the upward arc) and you'll see a positive slope (positive acceleration) and then negative acceleration due to gravity.
The guy in the video just misspoke, or didn't really know what he was talking about lol
@iloveihop07 The ball cannot accelerate after it leaves the trebuchet regardless of the energy it has been given. Acceleration can be equated to force divided by mass or F=ma. Therefore for any acceleration to occur a force must be exerted on a mass. This force is provided by the trebuchet but only when it is still in contact with the fireball. As soon as the interaction stops, there is no longer any force acting on the ball (at least from the trebuchet) and it cannot continue to accelerate.
@GoodwoodRRClub actually weight is the force which is acting on the fire ball and it acts down wards thats why the fire ball decelerates as it was going upwards then changed direction and started accelerating towards the ground if there is no forces acting on the fire ball the ball would continue flying in a constant speed after being thrown
@nonyspace Yes, you are totally correct. I have got myself confused between speed an velocity. I was referring to any horizontal acceleration rather than any vertical acceleration. You are right in saying that weight is a force which induces constant vertical acceleration in a downwards direction as shown by the arc of the fireball (any change in direction is of course an acceleration) but I meant to say that the horizontal component of the velocity of the ball is a constant.
@Vaylemn Similar idea to throwing a ball up, it starts to reduce in speed as soon as it leaves your hand. Reminds me of the old cricket commentator's howler, "and there goes the ball accelerating towards the boundry" which is nonsense it can only slow down after leaving the bat (assuming a level ground, I seem to recall some of those WI grounds are sloped...:)

Isn't it incorrect that it's a Speed-Time graph that was drawn instead of Velocity-Time since there is no such thing as negative speed.
