Key Equations

Newton's first law of motion

F_{net} = 0

Σ F = 0

Newton’s second law of motion	$F_{net} = m a$ or $Σ F = m a$
Newton’s second law of motion to solve acceleration	$a = \frac{F_{net}}{m} or a = \frac{Σ F}{m}$
Newton’s second law of motion to solve weight	$W = m g$

normal force for a nonaccelerating horizontal surface	$N = m g$
tension for an object at rest	$T = m g$
