Projectile Motion

Also known as: trajectory, ballistic motion

definition

Motion of an object thrown or launched, moving under gravity with an initial velocity. Models everything from sports to artillery to spacecraft launches.

💡 Intuition

A thrown ball follows a curved path—horizontal motion is steady, vertical is accelerated.

Core Idea

Horizontal and vertical motions are independent—analyze separately, then combine.

🔬 Example

A ball thrown at 45° travels farthest; at 90° it goes straight up and down.

🎯 Why It Matters

Models everything from sports to artillery to spacecraft launches.

⚠️ Common Confusion

The horizontal velocity stays constant (no horizontal acceleration).

How Projectile Motion Connects to Other Ideas

To understand projectile motion, you should first be comfortable with free fall, velocity and vectors. Once you have a solid grasp of projectile motion, you can move on to circular motion.
