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].

The mystery behind the self-siphoning beads
That is a cool video! They also link to an "explainer video".
Once a few beads are free to fall, they do (because of gravity). Falling converts potential energy to kinetic energy, but they share thei …

Every action has an equal and opposite reaction. Is is true for torques as well?
Yes, but the opposite reaction torque is not always useful.
If you defined torque as $\tau = r \times F$, then the force $F$ always follows Newton's third law. For any contact force, $r$ is the same. …

In 4 spatial dimensions, would motion under a central force law be confined to a plane?
As answered elsewhere, yes, the motion is confined to a plane.
For me, analogy to cross products is less intuitive in higher dimensions. What makes it planar? Force dictates the second derivative. Yo …
