Question

Which statements describe projectile motion? Check all that apply.

Projectile motion involves only vertical motion.
Projectile motion involves only horizontal motion.
Projectile motion is a combination of horizontal and vertical motion.
The horizontal and vertical motions of a projectile are independent.
The horizontal and vertical motions of a projectile are dependent on each other.

Answer 1

Correct choices:

- Projectile motion is a combination of horizontal and vertical motion.
- The horizontal and vertical motions of a projectile are independent.

(Assuming no air resistance: horizontal motion has constant velocity, vertical motion is uniformly accelerated by gravity, and the two components do not affect each other.)
