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

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.

Projectile Motion

Horizontal / Vertical Motion Demonstration #1

Constant horizontal velocity

Horizontal and vertical motions are independent of one another and can therefore be analyzed separately.

Projectile Motion

Horizontal / Vertical Motion Demonstration #2

Horizontal and vertical motions are independent of one another and can therefore be analyzed separately.
