Objects of different masses fall at the same rate due to the constant acceleration of gravity, which is approximately 9.81 m/s² on Earth. In an ideal scenario without air resistance, both a ten-ton weight and a golf ball would hit the ground simultaneously when dropped from the same height. Although the force exerted by gravity increases with mass, it does not affect the rate of fall. This principle demonstrates that mass does not influence the acceleration of falling objects. Understanding this concept is essential in physics and helps clarify misconceptions about gravity and motion.

Do objects of different mass fall at the same rate? If yes or no, why?
Objects of different masses fall with the same acceleration. This is because the acceleration due to gravity on the surface of the Earth is constant (in an ideal model) which equals 9.81 m/s^2. If you dropped a ten ton weight and a golf ball from a tower, they would hit the floor at the same time (not taking into account air resistance). However the force on the objects will be different. The larger the mass, the larger the force due to gravity.
Kindly see the attached pdf. My attempt to solve it, is in it.
I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction.
I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
