Physics Form 4: Chapter 2 - Forces in Equilibrium
object is at equilibrium
, then the forces are balanced which means that
resultant force is zero
. According to F = ma, the object's acceleration also zero when force in equilibrium achieved.
An object at equilibrium is either ...
at rest and staying at rest, or
in motion and continuing in motion with the same speed and direction
Object at equilibrium position. The load is static.
Force A = 3.4 N at an angle of 161 degree
Force B = 9.2 N at an angle of 70 degree
Force C = 9.8 N at an angle of 270 degree
