**Learning Objectives**

- Recall that a projectile has vertical and horizontal motion.
- Recall and use the independence of these motions.
- Use equations of motion to analyse the vertical motion.
- Find the resultant of the vertical and horizontal motions.
- Find the range of a projectile thrown at an angle.

__Key Questions__

- What are the general principles of projectile motion?
- What happens when a ball is thrown into the air?
- What happens then we throw the ball forward horizontally?
- What happens when we throw a projectile up at an angle?
