Newtonian mechanics discusses the movement of classical bodies under the influence of forces by applying Newton’s three laws. For more general concepts, use [classical-mechanics]. For Newton’s description of gravity, use [newtonian-gravity].

Uniform circular motion [pendulum]
The direction of R will be perpendicular to the surface of the cone with apex angle alpha.
The direction of normal reaction is always perpendicular to the concerned surface.
Therefore if you Break it …

Torque and force
Force due to torque will not depend on the mass of the wheel.
If the mass of the wheel is more, more amount of work needs to be done on the wheel. But we are not caring about that.
Remember here we …

If the net external moment on a body about a point is zero
If net external moment of some forces is zero about a point, then the net external force passes through the point
It means that when n number of forces are acting on a body,and if about certain poin …

What's wrong in stating that equal gravitational forces act on two identical masses at diffe...
Since you have placed one body higher than the other .Both will will not have the same acceleration 'g'.
I have assumed that both the body has same mass.
g ( acceleration due to gravity ) varies with …

Will the acceleration of a triangular wedge affect relative acceleration of a particle paral...
With respect to wedge , there will be no effect on the acceleration of the body,when you accelerate the wedge.
But with ground frame of reference , motion will change according to acceleration of the …

Area Swept by particle under central forces is an approximation
From Kepler's second law, we infer, the conservation of angular momentum is equivalent to saying the areal velocity is constant,
And the proof goes like this
$$ mr^2{\dot\theta=L}
$$
where $L$ is angu …
