Identify the example/s of Static Equilibrium: I. A book lying on a horizontal tableII. A buildingIII. A bridge
Correct answer: E. I, II and III
- A. I only
- B. II and III only
- C. I and III only
- D. III only
- E. I, II and III
Explanation
Static equilibrium refers to any system where the sum of the forces, and torque, on every particle of the system happens to be zero. All of the options mentioned above have net torque of zero hence all are under static equilibrium.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
