A paratrooper falling with uniform velocity is an example of
Correct answer: D. Dynamic equilibrium.
- A. Static equilibrium.
- B. Stable equilibrium.
- C. Unstable equilibrium.
- D. Dynamic equilibrium.
Explanation
Dynamic equilibrium occurs when an object is moving at a constant velocity (zero acceleration) and the net force acting on it is zero. In the case of a paratrooper, once they reach terminal velocity, the force of air resistance balances the force of gravity, resulting in a net force of zero and constant downward velocity.

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.
