Yes, it is possible for an object to have zero acceleration even when several forces are acting on it. This situation occurs when the forces acting on the object are balanced or cancel each other out.
According to Newton's second law of motion:
\(F_{net}=m⋅a\)
If an object experiences multiple forces, the net force is the vector sum of all these forces. If the forces are such that their magnitudes and directions balance each other out, the net force becomes zero \((F_{net}=0)\).
In this case, according to Newton's second law, the acceleration of the object will be zero \((a=0)\), even though there are forces acting on it. This scenario is often described as a state of equilibrium, where the object is either at rest or moving with a constant velocity.

Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.
W = Force × Distance
Where,
Work (W) is equal to the force (f) time the distance.
W = F d Cos θ
Where,
W = Amount of work, F = Vector of force, D = Magnitude of displacement, and θ = Angle between the vector of force and vector of displacement.
The SI unit for the work is the joule (J), and it is defined as the work done by a force of 1 Newton in moving an object for a distance of one unit meter in the direction of the force.
Work formula is used to measure the amount of work done, force, or displacement in any maths or real-life problem. It is written as in Newton meter or Nm.
