[[Force and Translational Dynamics]]

Force is a vector quantity measured in Newtons ($N$) caused by interactions between objects and systems.

A Newton in terms of other units is $\frac{(kg)(m)}{s^2}$.

# Free-Body Diagrams
Free body diagrams show all the forces acting on a single object.

typically used to figure out equations.

aligning the objects coordinate system to be parallel or perpendicular to the accelerations makes it easier.
