SparkNotes: SAT Physics: Two-Dimensional Motion with Uniform Acceleration
Since the forces acting on a particle always form a concurrent system, the equilibrium of forces gives the necessary and sufficient condition for ...
A force is applied to a particle free to rotate about a fixed axis. Force is shown decomposed into perpendicular and parallel components.
