What key factor affects the trajectory of a fired projectile?

• A. Wind resistance
• B. Gravity
• C. Barometric pressure
• D. Temperature

Answer: (B)

The trajectory of a fired projectile is primarily influenced by gravity, which acts on the projectile throughout its entire flight path. Gravity pulls the projectile downward, causing it to follow a curved trajectory rather than a straight line. This effect becomes particularly important as the distance the projectile travels increases, leading to a noticeable drop over time and distance.

The understanding of how gravity interacts with projectile motion is vital for accurate targeting, especially in military operations where precise calculations can impact the success of the mission. While factors such as wind resistance, barometric pressure, and temperature can also affect a projectile’s flight, gravity is the fundamental force guiding its path downward, making it the most significant factor in determining trajectory.
