Question
State any three factors which affect the projectile trajectory.

Answer
Factors Affecting Projectile Trajectory:
- Angle of Projection: Any object, when projected at different angles as shown in the figure, covers different distances. When it is projected or released at the angle of 30°, making a parabolic path, it covers less distance i.e., AB. When it is projected at the angle of 60°, it covers a distance i.e., AC and when it is released at the angle of 45°, making a parabolic path it covers the maximum distance i.e., AD.
- Projection Height Relevant to the Landing Surface: If the height of the projection and the landing surface is equal, then release the object at the angle of 45o. If the level of the landing surface is more than the height of projection, increase the angle of projection, which means it should be more than 45o. If the level of landing surface is less than the height of projection, decrease the angle of projection, which means less than 45o. So, the horizontal distance ofan object depends on the relevancy of projection height and landing surface.
- Initial Velocity: The distance covered by an object depends on the initial velocity of the projectile. If the initial velocity is more, the object covers a maximum distance. On the other hand, if initial velocity is less, the object covers less distance.
