Is there a more reliable way to code a projectiles movement and hit detection?

Hi, Is there a better way for projectiles to move then velocity because I'm currently using the roblox physics velocity because I want gravity to affect my projectile but they seem to be too fast for a touched event to react to the hit thus causing the projectile to pass right through.

Is there a better way to move projectiles with gravity thanvelocity x lookvector also is using touched event good or is there a more reliable way to detect hits.
