Why is it important to have a good foundation in understanding free fall motion before learning about projectile motion?

• Because free fall motion is more complex.

• Because it involves horizontal motion.

• Because it is unrelated to projectile motion.

• Because it helps in understanding the vertical component of projectile motion.
