When throwing a projectile when moving sideways the project should keep the player's direction momentum. This is the case in Java edition, causing it to have diagonal velocity. This is not the case in Bedrock edition. When thrown, projectiles will only have velocity in the direction it was thrown with no impact based on the player's actions. Thus, the Bedrock projectiles do not follow the laws of motion.

This is most obvious with wind charges, when moving sideways and throwing it in Java edition, it gets diagonal momentum. In Bedrock Edition it just goes straight.

When you throw any projectile while walking sideways in the image below it should land near the target block rather than the red concrete. This is the case in Java Edition but not Bedrock.

Steps to Reproduce:

1. Get a wind charge
2. Move sideways and throw it
   The snowball goes straight instead of diagonal, not following player movement
