Question

Which of the following is NOT the factor affecting projectile trajectory?

• A. Gravity
• B. Angle of release
• C. Buoyant force
• D. Air resistance

Hint:

In projectile motion, the main factors affecting the trajectory are gravity, angle of release, and air resistance. Buoyant force is not relevant in this context unless the projectile is moving through a fluid.

Answer 1

The Correct Option is C

Step 1: Understanding projectile trajectory.
Projectile trajectory is influenced by several factors that determine the path of an object in flight, such as gravity, the angle of release, and air resistance. Step 2: Identifying the factors affecting trajectory.
- Gravity pulls the object down, causing a parabolic trajectory. - The angle of release determines the initial direction of the projectile, affecting the range and height. - Air resistance opposes the motion of the projectile and alters its speed and trajectory. Step 3: Comparison with the other options.

• (A) Gravity: Correct. Gravity is a key factor in determining the path of a projectile.
• (B) Angle of release: Correct. The angle at which a projectile is launched significantly affects its trajectory.
• (C) Buoyant force: Incorrect. Buoyant force, which relates to the force exerted by a fluid on an object submerged in it, does not affect the trajectory of a projectile in air.
• (D) Air resistance: Correct. Air resistance plays a significant role in slowing down a projectile and influencing its path.

Step 4: Conclusion.
Therefore, the correct answer is (C) Buoyant force, as it does not affect the projectile's trajectory. Final Answer:} Buoyant force.
