How does the inertial ball experiment work?
I’ve been trying to analyze and gain a greater understanding about this experiment, however I have I do not fully grasp how the system works.
as far as i can understand:
Also, how can I model and describe this experiment using mathematics...
I'm looking for something that can pull on a string at a constant force per second
So that i can graph Force (n) over Time (s) just like that:
in this graph, the red line represents the tension of a string as i pull on it. However, i really need that slope to be constant.
By the I'm...
thanks for your comments,
now i understand what's happening conceptually? but how do i represent this using math?
net torque = (angular momentum) / (time) = (moment of inertia) x (angular acceleration)
using math, how can i show that, if the roll is pulled at a certain velocity, the...
I'm extremely excited to embark on my physics project and it has all to do with ripping toilet paper rolls.
As it is commonly known, when a full toilet paper roll is given a fast jerk, a sheet breaks off. However, as the roll is gradually used up, a faster jerk has to be applied or the...
hmm so is this how an isotherm work
say when the gas is heated, the pressure increases and thus the molecules transfers its energy to the wall and work is done till the pressure equalizes the atmospheric pressure.
at this point, since the molecules transferred its energy to the walls ...
thanks g01 and rbj for the replies
i grasp what you mean now
one more question: change in internal energy = - work done by system
please explain how this occurs on a molecular level?
I can see how q = w from the equations by can't quite grasp this conceptually.
doesn't adding heat increase the internal energy? and thus when volume expands it only does so so that the pressure equalizes atmospheric pressure.
i can visualize volume increasing and pressure dropping when...
We are currently learning about isothermal processes in class and there's something i don't really get.
i can visualize what happens when the piston is pulled or pushed very slowly, PV = constant and hence produces an isotherm on a PV diagram.
And if since the temperature is constant...
ah so it really depends on the atomic structure of the material. If so, how does metallic, covalent and ionic compounds compare. Is one generally more conductive than the other, or it really depends?
Thankas cristo
no, it's not a homework question. Just asking because i feel curious
after thinking about it for abit, i guess that the rate of conduction is related to the density of the object. So... a solid is a better conductor than a gas because the atoms in a solid are closer together. However is this...
Why do warm air hold more moisture than cold air?
Is it because the volume of warm air is larger than cold air because warm air expands?
How can strong winds be cold, how do they work?
If the movement of air is fast, then wouldn't it heat the body of air up? Are strong winds a moving...
centripetal force is always constant. The independent variable would be the radius, because in this lab we are trying to see how radius affects the speed for a given centripetal force.
Yes, the magnitude of centripetal force is provided the weight hanging from the string in the center
Anyone...
