AThe force acting normally on a surface
BThe pressure acting on a surface
CThe weight of air on a surface
DThe energy stored in a surface
Answer & Solution
Correct answer: A. The force acting normally on a surface
1. Section 4.1 defines thrust.
2. A force can act in any direction on a surface.
3. Force normal (perpendicular) to the surface is called thrust.
4. So option A is correct.
