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].

Understanding the relationship between the spring constant and the angular frequency
Since pendulum undergoes rotation around the point at which is suspended, it is more convenient to talk in terms of "Moment which the force exerts (as opposed to talking in terms of force alone)" and …

In rotational motion why total gravitational force act on centre of mass (centre of gravity)?
Because a rigid body acts like its entire mass is contained within a point called center of mass. This greatly simplifies solving problems such as those in your examples. But in principle you can adop …

Why conservation of energy does not apply in this case?
Energy is not conserved here due to friction. Same case when you have inelastic collision. There energy is not conserved, but linear momentum is.
Here angular momentum is conserved because no external …
