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 '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
