If gravity were increased, how would it change the spring constant for a given spring?
I was just wondering how the value of a spring constant would change if gravity were increased. Agreeing that gravity is 9.8 m/$s^2$, if, for example, gravity was changed to 15 m/$s^2$ with nothing ...

Newton's Third Law of Motion and Gravity
I have another question about the third law of Newton (if you can check the last one that I posted) :
Why is it that the gravity that pushes me on the Earth is so powerful, but the reaction force (...

Does Newton's law fail here? [duplicate]
So you are holding a thin horizontal rod (which is not bendable) which is fairly heavy and there is a heavy object (lets say a bag full of heavy stuffs) hanging from it.
So now if the bag is shifted ...

Newton's 3rd law and normal force
There is something I hope you can help me understand...
According to my physics course, when I stand on the surface of earth, the normal force prevents me from "falling down" because it's ...

Normal component of force exerted
Suppose a simple setup where a free load (red) is supported by an inclined plane (pink) and a block at the end of the inclined plane (blue) touching the load as shown:
Is the force normal to the pink ...

Is weight = Gravitational Force - Centripetal force?
Is weight ≠ gravitational force, for an object on the Earth’s surface? Why is this? Is it because part of the gravitational force acts as a centripetal force? Does the normal contact force not nullify ...

What is weight at the particle level? How EXACTLY do atoms exert weight on each other?
This is what my intuition says about how the concept of weight works in a solid.
The light brown arrows are the vectors of gravitational force, the light gray parts are the electron clouds around ...

Understanding the concept of energy in a vertical spring system
I have a concept I don't think I get well. I would like to clear out a couple of things. Consider the following system:
The spring on the left is the one on the right after extension from equilibrium....

How to calculate pressure/force on a triangle vertex? [closed]
Assuming those are identical triangles. We add some weights on the upper bar. The only difference is with the location of the weights and the size of the weights. Is there any difference on the ...

Net Force of Equal and Opposite Gravitational Forces Don't Equal Zero? [duplicate]
I've come across this question, and I'm at at a loss.
Two masses, m and M, are in an isolated system. The gravitational forces, F (by M on m) and F (by m on M), are equal and opposite. Why do they ...

Why do we feel weightlessness during free fall?
An object in free fall accelerates towards the Earth at a acceleration equal to $g$ (the accleration due to gravity). Now if we ignore the air resistance, why do we feel weightlessness? I could not ...

If a ball is kept on the table, then what forces are being exerted on it?
If a ball is kept on a table then there is gravity acting on it as well as a normal reaction force by the table on the ball. But as both the forces are being exerted on the same object i.e. the ball, ...
