Why do ballistic missiles fall in some circumstances of precision?
Correct answer: D. All of these
- A. Due to their shape
- B. Due to air resistance
- C. Due to the angle of projection
- D. All of these
Explanation
This option suggests that imprecision in ballistic missiles can be influenced by a combination of factors-shape, air resistance, and angle of projection. While each factor plays a role, none singularly defines the reason behind imprecision.

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.
