Question

Consider a projectile. Which of the following describes y-motion? Check all that apply.

1. The y motion is a vertical motion.
2. The y motion is a horizontal motion
3. A projectile covers different distances per second in the direction.
4. A projectile covers equal distance per second in this direction

Answer 1

1. True - gravity affects the y motion

2. False - x-coordinates affect the horizontal motion

3. y because gravity affects motion in the y-direction

4. x generally no external forces act in the x direction and hence no acceleration in the x direction
