Free-Body & Net-Force Builder

Push on the block from four sides. The net force (coral) is the vector sum; the acceleration (navy, dashed) follows a = F_net / m, same direction as F_net.

→ applied forces → net force ⇢ acceleration

F_net,x = N F_net,y = N

|F_net| = N

direction:

|a| = m/s²

push right12 N

push left4 N

push up6 N

push down0 N

mass m2 kg

Try: set right = left and up = down. F_net = 0, so a = 0 — the object is in equilibrium even though four forces act on it.
