Is this why feathers fall slower than canon balls?

    Balls Fall
AI Thread Summary
Objects of different masses fall at the same rate in a vacuum due to gravitational acceleration being constant, but air resistance alters this in real-world conditions. A cannonball, having greater mass and weight, takes longer to reach a point where drag equals its weight compared to a feather. The feather achieves uniform speed quickly due to its low mass, resulting in a slower fall. Additionally, the shape and density of the objects significantly influence their falling speeds. Therefore, the differences in fall rates between a feather and a cannonball can be attributed to air resistance and their respective physical characteristics.

Two objects of different mass should fall at the same time, both with acceleration g. That is if the objects are in a vacuum, have the same initial speed and height. However, considering air resistance, the acceleration diminishes until both the drag and the weight are equal. Now, a canon ball has a larger mass and weight than a feather. So according to this, am I right to assume it would take a longer time before it achieves equal weight and drag than a feather thus gaining a greater velocity?

I would think the feather quickly obtains uniform speed due to its very low mass and that is why it falls slowly. Is this right?

Shape and density are important factors.

A small ball and a large ball of the same material would fall at the same speed.
 

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'

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...
