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.

In a simple pendulum, $\alpha$ is angle between string and vertical, $T$ is tension in string and $mg$ be pull on the bob.
$T$ has 2 component $T\cos\alpha$ and $T\sin\alpha$
$mg$ has 2 components $mg …

Can potential energy be treated as vector quantity?
Force can be representd by potential energy function which for 1 dimension case satisfies the derivatives condition $f(x)=-d U(x)/d x$.
If we now consider 3D space, then position will now depends on c …
