Question

fill in the blank question after an initial force launches a projectile, the only force acting on it as it moves through the air is, which causes its trajectory to curve downward. you can determine a projectiles trajectory if you know its initial. need help? review these concept resources. read about the concept

Explanation:

1. For projectile motion (ignoring air resistance), the only force acting on the object after launch is gravitational force, which pulls it downward and creates the curved trajectory.
2. To determine the full trajectory of a projectile, you need to know its initial velocity (which includes both speed and direction, as these define the starting motion combined with gravity).

Answer:

After an initial force launches a projectile, the only force acting on it as it moves through the air is gravity, which causes its trajectory to curve downward. You can determine a projectile's trajectory if you know its initial velocity.
