MDCAT Physics QUESTION #4384
Question 1
When an object attains terminal velocity, its acceleration is:
  • $9.8\ m/s^2$
  • Zero✔️
  • $1\ m/s^2$
  • $9.8\ m/s^2$ downward
Correct Answer Explanation
At terminal velocity, the net force on the object is zero — drag force equals gravitational force. By Newton's second law: $F_{net} = ma = 0$, so acceleration $a = 0$.
