The trajectory of projectile is
- A semicircle
- B an ellipse
- C a parabola always
- D a parabola in the absence of air resistance
Answer & Solution
Correct Answer
(D) a parabola in the absence of air resistance
Step-by-step Solution
Detailed explanation
The trajectory of a projectile is a parabola in the absence of air resistance.
In the presence of air resistance, range and maximum height of projectile, both will decrease, hence path of projectile will not remain parabolic.
In the presence of air resistance, range and maximum height of projectile, both will decrease, hence path of projectile will not remain parabolic.
