This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

Please help me with this doubt from center of mass concept
Take the case of Atwood machine where masses of blocks are $m$ and $2m$.
The acceleration of individual masses are $\frac g3$. now the acceleration of center of mass of masses and string system is $ …

String applying a force on pulley
Why should string apply a force on pulley? (like atwood machine cases) and does that mean the pulley will exert an equal force on string (newton's third law)?
Please explain in detail,if possible exp …

Condition for looping the loop
Consider a ball tied to a string and it is imparted a velocity we have studied that condition for looping the loop is that tension at the uppermost point must be zero, but why is this condition impose …
