Projectile is like a cannon shooting a ball so it will be in "free fall"
While in free fall you are subject to gravity pulling the ball down.
Also since it's flying through the air there is air resistance.
So GRAVITY AND AIR RESISTANCE
hope it helped
Answer:
gravity and air resistance
Explanation:
As the ball is moving in projectile motion it has to overcome the Earth’s force of gravity which is acting on the ball and pulling it downwards. Also the ball has to overcome the resistance offered by the air particles which tends to pull the ball in the backward direction opposing its forward motion.
