If air resistance is negligible, the acceleration of all projectiles is exactly the same. True or false?

Answer 1

False. The acceleration of projectiles is not affected by air resistance, but it can vary depending on the initial velocity and launch angle of the projectile. For example, a projectile launched at a higher initial velocity or at a steeper launch angle will have a different acceleration compared to a projectile with a lower initial velocity or a shallower launch angle.
