The trajectory of a projectile flying against a strong air current is
Correct answer: D. Not a parabola
- A. Straight line
- B. Parabola
- C. Hyperbola
- D. Not a parabola
Explanation
This option aligns with the real scenario. When a projectile faces a strong air current, the combined effect of air resistance and gravity alters its trajectory, causing it to deviate from the idealized parabolic path seen in the absence of air resistance.

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.
