The horizontal motion of a projectile is considered...

• motion with constant acceleration

• uniform motion

• the same as the vertical motion

• dependent on the vertical motion.

The vertical motion of a projectile is considered...

• motion with constant velocity

• independent of the horizontal motion

• uniform motion

Suppose you shoot a basketball into a hoop successfully. What happens?

• I miss because I can't shoot.

• The ball is launched at a specific angle / direction and velocity.

• The ball follows a linear path to the hoop.

• The ball goes straight up into the air, reaching a maximum height, and then falls back down to where it was thrown.
