Well, I think it does. But the reason i asked this STUPID question is this:
If the white ball stops then it means all of its kinetic energy has been converted into the kinetic energy of the other ball(assuming that there are no energy losses), right?
(in the following example I've assumed that...
In snooker, I've noticed many times that it you hit some ball in right place the white ball will stop at the point of contact but the ball that was hit starts moving. Is this true that the white ball tranfers all of its momentum to the other ball and since there is no more momentum left it stops?
I feel the same way man. Its not actually in my maths book its in my addition Mathematics book(o'levels). They even had particle machanics in it with work energy power. I had the option to choose biology or Additional mathematics and I chose Additional Maths.
By the way thats for replying...
What is relative velocity? I have solved alot of questions relating to it but I'm still confused what EXACTLY is it? Its in my maths book so my mathematics teacher was not able describe this in detail. One more thing: I'll be much pleased if someone also explains what is relative path.
Thanks...
The following table given in my book shows it doesnt:
Substance________Speed of sound(m/s)___________Density(kg/m3)
Air___________________330_____________________1.29
Oxygen_______________320_____________________1.43
Aluminium_____________5100____________________2710...
I have three questions about sound waves. I could have asked my physics teacher but he fails to answer almost all the question out of our syllabus. :mad:
1- We have read that the speed of sound in solids doesnt depend on their desities. If thats the case then they depend on what thing?
2-...
Cant we use the formula 'hpg' to calculate the pressure? Because what i've learnt so far (i've just started A'levels) pressure of a fluid depends on its depth not on the width/diameter of the container. I can be wrong. If it is the case please dont make fun of me and do correct me.
