The object at equilibrium may have any:
Correct answer: C. Velocity
- A. Force acting upon it
- B. Acceleration
- C. Velocity
- D. Torque acting upon it
Explanation
A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero. If an object is at equilibrium, then the forces are balanced. Balanced is the keyword that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
