* Neglecting Air Resistance: In the ideal scenario where air resistance is ignored, the only force acting on the projectile after launch is gravity. Gravity acts vertically downwards, causing the projectile to accelerate downwards.
* Horizontal Velocity Remains Constant: Since there is no horizontal force acting on the projectile, its horizontal velocity remains constant throughout its flight. This means there is no horizontal acceleration.
Important Note: In real-world situations, air resistance does play a role. Air resistance creates a force that opposes the projectile's motion, causing a slight deceleration in the horizontal direction. However, for many basic projectile motion problems, air resistance is often neglected for simplicity.
