Pay close attention to how the manual handles English units (slugs vs. pounds mass) versus SI units (kilograms vs. Newtons). Mismanaging
If you have more unknowns than force equations, use kinematic relationships (such as ) to bridge the gap. Pay close attention to how the manual handles
Used when a particle moves along a straight path or when forces are easily broken down into orthogonal horizontal and vertical components.
