Classical mechanics discusses the behaviour of macroscopic bodies under the influence of forces (without necessarily specifying the origin of these forces). If it's possible, USE MORE SPECIFIC TAGS like [newtonian-mechanics], [lagrangian-formalism], and [hamiltonian-formalism].

Informal book on Classical Mechanics
Actually Taylor's book is informal and a good introduction to the Classical Mechanics. But it is by no means at the level of Goldstein. You can start with Taylor, but eventually you have to go for Gol …

Applied Force in a Non-inertial Frame
Let us consider two reference frames: $S$ and $S'$. $S$ is an inertial frame and $S'$ is a non-inertial frame as it is rotating wrt $S$ with an angular velocity $\omega$ about a fixed axis. The origin …

Coordinate Transformation in Mass-Pulley Problems
Let's say we want to determine the tension $T$ of the rope in the setup above.
For the mass $m_1$, in $XOY$ coordinate system, Newton's 2nd law yields
$$m_1 a_1 \, \hat{x} = T \, \hat{x} - m_1 g …

Lagrangian for Non-inertial Frame
Context
Let us consider two reference frames: $S$ and $S'$. $S'$ is rotating with respect to $S$ with an angular velocity $\vec{\omega}$ about a rotation axis $MOM'$. The origins of $S$ and $S'$ are …

The $r$-component of the Total Force on a Simple Pendulum
Let us consider a simple pendulum in vacuum. Its bob has a mass $m$. There are two forces acting on the bob: the tension of the string $\textbf{T}$ and the uniform gravitational force, $\textbf{W} = m …
