1. Projectile Motion
Projectile - an object for which the only force acting upon it is gravity. The force of air resistance is negligibly small or nonexistent for a projectile.
Horizontal / Vertical Motion Demonstration #1
No horizontal velocity

2. Projectile Motion
Projectile - an object for which the only force acting upon it is gravity. The force of air resistance is negligibly small or nonexistent for a projectile.
Horizontal / Vertical Motion Demonstration #1
Constant horizontal velocity
Horizontal and vertical motions are independent of one another and can therefore be analyzed separately.

3. Projectile Motion Horizontal / Vertical Motion Demonstration #2
Vertically
for both balls
Horizontal and vertical motions are independent of one another and can therefore be analyzed separately.

4. Horizontal
Since there are not any horizontal forces
Because of Newton’s First Law
