Do Mass and Friction Affect Velocity on an Inclined Plane?

AI Thread Summary
Two blocks of different masses rolling down an inclined plane will have the same velocity if there is no friction, as gravity affects all objects equally regardless of mass. The discussion also raises a question about whether removing metal rods from a plastic boat and placing them in a tub will cause the water level to rise, which relates to the principles of displacement. Participants encourage sharing existing knowledge to better address these questions, emphasizing the importance of understanding gravity and motion on an incline. The conversation highlights the need for foundational concepts in physics to solve these problems effectively. Engaging with these questions can enhance comprehension of basic physical principles.

1.) if there are two blocks of different masses rolling down an inclined plane, will their velocity be same? if so then how? there's no friction between the plane and the blocks.

2.) there is a plastic boat in a tub, filled with metal rods. if the metal rods are taken out of the boat and put into the tub, will the level of water in the tub rise? please explain this with basic concepts.

Good questions. How would you answer them?
 
i don't know. that's why i posted it!
 
thanks! :D
but what about the other question? :(

Well, these sound a lot like homework questions. The best way for us to help is for you to tell us what you've come up with so far and where you are stuck.

For the first one, what do you know about gravity and falling objects? How is motion down an incline different from just falling?

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
