two spiring balances
My 9th grade textbook says when we set a apparatus by the following procedure "tie the free end of two spring balances X and Y together and name this intersection A and then fix the rigid end of sprin …

Does energy transmission depend on the speed of incoming particle?
Since a few past days , I am struggling with finding an in depth atomic model of force exchange between colliding paricles (originally newtons third law) , because at this point of time i am unable to …

Conservation of momentum always? [closed]
Consider two atoms A and B, with A at rest and B in motion towards A.
As soon as B is in the atomic field of A, will it stop with its energy going into B or will it just move up to a postion where th …

Conventions and realities of kinetic energy?
I am having doubts regarding why $1/2$ is present in kinetic energy and if this is conventional why cant we say potential energy is $2mgh$ and kinetic energy $mv^2$. So is this $1/2$ conventional or n …

Changing momentum of moving trolley
"velocity would stay constant, mass would decrease and so the momentum of the trolley decreases" , is a correct argument , but if this is a system where gravitational forces are present , you have neg …

Change of energy into friction?
If I am pushing a car and it does not move, I am doing no mechanical work. However, I am changing the energy that was stored in my cells into heat energy (maybe sound energy if my hand slips off the …

Newton's third law at the quantum level? [closed]
let's look at force at the atomic level to understand the newtons third law of motion. I'll use Helium atoms as an example.
Now imagine we start with one atom HE2 stationary, and throw another atom …

conservation of momentum? [closed]
At hyperphysics I got this image, with the same description in text as is in this image
It says that when a massive particle (say $A$) moving with a velocity collides with an object having a relat …
